INTERVIEW TITLED "REASON PENTAX HAVE CHANGED"
Since the announcement of K10D, it hyped up the market, and even after the release, all stock are gone quickly. They had to delay the release for the necessity to "stock up" which was obviously a drop in a bucket. Although Pentax products have been enjoying quiet and lasting popularity, there has been no case like this time. As various articles and reviews about K10D itself are everywhere, we interviewed Mr.Tatamiya about the background of the development of K10D in order to explore why they could produce popular products beginning K100D.
Wildly different sales from forecast
Q Because of attractive spec of K10D, it was easy to anticipate the popularity in Japan domestic market, but it was also very popular in Photokina booth held in Europe which was traditionally a weak market for Pentax brand.
In Japan, people were already anticipating a possibility of stock shortage even before pre-booking stage. How Pentax have been viewing these market reactions?
A There was a K100D this year which was very popular, and we naturally expected that K10D sales would be good too. In spite of this, we never expected the pre-booking situation before the release. We were truly surprised at the difference “by digits”.
Q You said the forecast was wildly different “by digits”. Is “by digits” a metaphor, or, were the digits really different from the forecast?
A We thought it was going to be popular, but not as popular as K100D, because K10D was still a sub $1,000 camera. However, although we cannot give you any specific figures, we were overwhelmed by far more than twice the pre-booking order qty of k100D. For example, a big chain store who pre-booked 300 units of K100D now gave us a pre-booking order of over 1,000 units. This is just in Japan but the market reaction in overseas market is much larger than that
Q We had an impression that Pentax brand was not particularly strong in Europe, but is it popular there too?
A Pentax brand has long been established in Japan, and there are many long time Pentax fans in North America. On the other hand in Europe, it was not particularly well recognized. However, the pre-release reception was excellent, and in certain country, Order of 1,000 units came in when we forecasted 50 units initial order based on the history there. Right now, the order level in Europe is as good as in Japan or North America which frankly caught us off-guard. In addition, as far as K10D is concerned, the reaction from Asian market, particularly Hong Kong and Korea, is overheating.
Organizational changes produced K10D?
Q There was a comment by Mr.Torigoe in his interview at Photokina that the atmosphere in the development front line has significantly changed. As a leader of the project, what are you feeling about this?
A Excellent market acceptance of K100D really has changed the atmosphere. Engineers are human too, and they were very happy to find that the products they produced were so well received in market. That became a strong motivation, and the last spurt in finishing phase of K10D was very “contents rich” and we are proud of it.
Q What do you mean by “contents rich”?
A Development staff for K100D and K100D is partly shared and overlapping. During 3 months since completion of k100D till last spurt for K10D, they voluntarily offered their utmost effort to polish up detail of features and performance specs, even though mid level camera has many more features and the work load and contents are heavy.
For example, relative to 3fps burst rate, it was barely achievable in the final stage. However, we still explored to see if it could be further improved by reevaluating tuning etc. The a development staff specialized on the feature came up with an innovation only he could come up with, reconstruct the tuning sequence and now at least 3fps is assured even under the most difficult exposure conditions. In reality, you can measure it to confirm that it is actually more than 3fps particularly under better conditions. If you trip the shutter, you can feel the speed of it.
Also, initially in RAW burst mode, it stopped when buffer was filled, after which simple writing in memory media continued. However, we designed a parallel writing in order to create as larger a room as possible in buffer so that additional 1 to 2fps could become possible. These attentions to detail were followed by each staff spontaneously, which resulted in accomplishing design specs, and in some cases, exceeding catalogue specs.
Q *istD and *istDS also were good products but they were not as popular as K100/10D. What has changed before and after K100D, and what part of the product concept do you think were accepted by market?
A It is true that the working motivation is boosted tremendously, but development staff never changed or their capability suddenly improved.
On the other hand, organizational structure has changed markedly. Production Planning dep’t in development team and marketing staff in sales company were independently operating but were consolidated into one in April 2005. This means the group that has been taking pulse of market and those take initiative in product development work together. The first product which this arrangement made a fruit was K100D.
Q In other words, reorganization to quickly grasp market needs and reflect them in products led to success?
A We were always grasping market needs but problem was our inability to consolidate them into one central location. By directly connecting marketing and development, it became possible to accurately target user demography by each product. There is always an opinion that SLRs after all are for those photo maniac and there is no marketing needed. However, in reality, people of various different needs are buying DSLRs. We thought we should develop products for each target market, so that they would be satisfied.
Taking advantage of smaller company’s merits
Q I see. Then, in the case of K100D, how are those design concepts exhibited?
A Regarding K10D, it means no middle of the road to satisfy everybody. Middle of the road which satisfies most everybody has to be taken care of by K100D. K10D is a one notch upgraded model, with easy picture modes eliminated, priority on features, weatherproofing and generally the sense of existence (weight and size) over just a compact package.
Q When we first encountered K10D, it felt rather heavy for Pentax who have been advocating lightweight and compactness. Weight by itself is not necessarily a bad thing but it is certainly different from past path.
A In the very early stage of the development, we already decided to incorporate what we thought were necessary features for a mid class body and associated parts without unduly shaving anything off. Weatherproofing was an important factor too. Then, all parts to be squeezed into a body were lined up and the final size/weight were determined. There was indeed a concern raised on size and weight by marketing people.
However, a model that prioritized small package and lightweight was K100D. Also, for the scope of features incorporated in this body, we believe it is still rather compact compared with competitions. K100D was for features and easier user interface over the compactness.
Q Traditionally, Pentax always have produced unique features to improve operability and user interface such as Hyper Manual etc. This time, a new exposure mode ISO priority mode and other new exposure modes were added. How were these features created?
A Pentax’s development staff all love cameras and photography and these engineers have been constantly suggesting a number of innovative features. But they were not particularly well adopted into new products in the past. However, aforementioned organizational change enabled those development staff having frequent discussions directly with core staff of product planning and marketing, which in turn encouraged submission of new ideas. We always speculated what type of people would purchase K10D, they must be those who prefer “real stuff”, then what’s the real stuff is etc etc.
In this context, we discussed a possibility of changing the basic concept of exposure control, so that users can choose what they think would be the best exposure mode depending on situations. It would be dumb if we could not maximize advantages of DSLR over film SLR. We examined various ways of operating DSLR, taking advantage of features of digital camera, which resulted in addition of two new modes.
Q Listening to you, in addition to the effect by organizational change, closer communications and freedom typically associated with smaller companies are producing flexible ideas.
A When market needs are conveyed to front line development, designers and engineers often bring solutions immediately. However, in large organizations wherein many layers accumulate, fast communication becomes difficult. In the case of K10D planning, marketing, product planning, designers and engineers had discussion from the users’ viewpoint on an equal level, which is reflected in detail of ideas and specs. Taking an example of RAW button, there have been various debates among us. Some say most users would prefer JPEG, yet others say they only shoot in RAW setting. In reality, there may be many users who usually shoot in JPEG, selecting RAW as required. Just adding a button affects on a lot of areas like mechanical design, firmware and user interface etc. However, as long as it is a conclusion based on detailed evaluation of true needs for user interface, the plan gets approved smoothly. Organization change actually derived Pentax’s advantages as a smaller company. We could align all necessary disciplines, i.e., mechanical design, electronics design and development team, focusing what users really need.
Dust reduction by “Knocking off” and “coating”
Q With regard to DR, what innovations, besides coating, are involved?
A Expression “dropping CCD” is often used to describe our DR system, but “knocking” is more accurate description as our DR utilizes the acceleration of SR actuator.
Q We of course assume that durability testing has been conducted….
A Yes, anybody would be concerned about it. We of course exchanged notes with CCD device maker regarding durability against shock up to so many G etc. Then we added sufficient safety margin to determine the mass acceleration, therefore, there is no concern on CCD deterioration or break of wire bonding etc.
The idea of dropping dust by knocking CCD element was patented a long time ago, but that was not enough. So we adopted a hard coating technology which our eyeglasses people had. This coating repels even oily substances by treating the surface at micro millimeter level. Then we discovered that the combination of hard coating and physical knocking was very effective for dust removal. If dust contains moisture or oil, it is absorbed onto surface and physical energy alone won’t remove it.
Q Any improvement in 2nd generation SR?
A CCD actuator was powered up and control programme was modified. At this point, actuator was enlarged, size of the unit and weight have substantially increased due to new CCD which was larger and heavier. Since the size/weight of complete CCD unit has increased anyway, we thought we might as well take advantage of it and strengthen SR. This also resulted in accuracy of SR as well.
Algorithm of control programme has been tuned to increase mainly the stability. In the past, there were certain situations wherein SR movement pattern was not quite satisfactory, but we tuned it by trial and error. By increasing actuator power, activation is fast and braking is easier which led to stable SR effect.
Cost distribution on true necessity rather than specification alone
Q Relative to image rendering, default setting is now “natural”, nevertheless, overall image/colour rendering now appears to be more straightforward. What has changed?
A Basic concept never changed since *istD. However, the performance of image processing engine has been improved and the higher degree of edge compensation for example has become possible. In edge processing, it does not appear too thick (rather fine) which might be making images look more refined. By using new processing engine, different image processing from before became possible, hence easier tuning.
Q Combination of new analogue front end (AFE) by Newcore Technology and the latest image processor by Fujitu seems to be very effective but what are the merits of this?
A We are not disclosing the detail of our image processor. Firmware was also developed by us. As you indicated, it is true that we now have a lot more elbowroom in image processing after AFE that now has a 22bit AD converter. Improvement of image processing boils down to speed. Memory is now a high speed DDR2 with broader bus bandwidth which is enabling image processing with sufficient margin.
Q Some are not too happy with 1/4000 shutter speed or 3fps burst rate, but I personally believe that it was the right approach to suppress these parts and redistributed the cost over weatherproofing etc. What is the reason why you were not particularly concerned about these figures (shutter speed, 3fps etc) ?
A Consider 10 years ago when people bragged about 1/8000 shutter and synchrospeed 1/250 which were considered norm for a decent body. In addition, lenses had to be F2.8 constant zoom. Today, these are not particularly important.
This means users became wiser and they are now able to judge by themselves what’s really important in getting images they want. Then digicam enabled sensitivity control at will, and people rather prefer compact lenses than those one stop faster, or easier operation over unnecessarily higher spec. Users needs now become diverse.
Knowing above, and if we still push for increased shutter speed and burst rate etc, it requires more robust mechanical design with higher speed shutter charge, mirror dumping and even increased SR reaction etc. Moreover, CCD readout has to be 4 channels and AFE has to be doubled. Technically, all these are completely feasible but it was obvious that the cost would increase, so does size/weight. So, we dropped these requirement in very early stage of development.
Q In other words, cost has been redistributed to something other than shutter speed or burst rate etc?
A This is the result of well thought-out selection of what’s really required for mid level body and severely scrutinized cost distribution. Not $3000~4000 body but we consciously set a price point which is affordable for the target market, whereby it became possible to materialize high performance and usability under conditions in which target users would use K10D.
In the future, we will continue to analyze what users really want, and develop models that can be truly useful in actual use, not just the spec sheet which might be easier to eyes.

INTERVIEW WITH K10D DEVELOPMENT ENGINEERS (PART I)
December 6, 2006
Challenge involving employing 10mp CCD which is not particularly advantageous in sensitivity control
First hurdle is actually produce image!
Q K10D finally adopted 10mp sensor, but was it not difficult to carry on the successful image processing using a new CCD?
A (Mr.I.Hirai, Imaging System Division, Development Dep’t)
Pixel pitch is smaller and the sensitivity is one stop disadvantageous (ISO 100~1600). This of course concerns high sensitivity noise and we were fully aware of it, and strived for “film-like quality”, which was always our goal. It is of course true that noise increases as sensitivity increases, but we wanted to make noise look more natural. Of special concern was not to create “digital-like” image due to unnatural suppression of noise by image processing. In order to achieve more natural looking images, various fine tunings were conducted.
Q K100D employed the same 6mp CCD as 8istD, DS2 and DL2. If over-emphasis on spec figures would be set aside, there seem to be more advantages of continuing using the same CCD for obtaining consistent and stable images. A brand new CCD was adopted this time, but was this approach really necessary?
A Trial and error continues until the last minute to the point people began to worry if the schedule could be maintained. But this is same for competition too.
With new CCD, the first difficulty is to produce actual images. It does not take long to produce acceptable level of images at the base sensitivity (ISO 100), however, as the sensitivity increases step by step, at some point, terrible images will be produced. True effort start from this point, trying to pin point possible reasons mainly by trial error, often having to make new Cbs (circuit boards). At the same time, firmware has been developing and each group has to closely coordinate in order to slowly improve image quality. Tuning can only commence after this.
Frequency of designing new CBs might be largest in K10D project.
Q What was the most difficult task in properly tuning images?
A It must be measures against noise. Homogeneous noise across whole image could often be permitted but countermeasures against localized noise is most difficult to achieve.
Q What would be the main reason for such localized noise?
A If we know it, life would be so much easier. Of course each case is closely analyzed and dealt with, but there are a number of cases of localized noise, and it is really time consuming to solve these. Changing CB’s is one measure but has to be repeated many times.
We were fully aware that we were going to face very critical eyes of users on noise issue because of increased resolution. In addition, base sensitivity of sensor was lower too, which made the tuning to the acceptable level for production very difficult.
Q Does this mean that measures at analogue signal stage might be important, since noise tend to come into a path between CCD and A/D converter?
A (by Mr.T.Hotta who was in charge of firmware design)
Indeed. Recent Cbs might look one piece but are actually layers, and slight change in wiring alone significantly changes how noise appear. In digicam, DDR2 memory that functions at very high frequency and many other parts that produce radio waves. A TV tuner portion of videocard for PC for example, is tightly shielded in order to avoid the interference between digital circuit and analogue circuit. If noise enter before digitization of signal, digital images output would almost be unusable. When increasing gain of sensitivity, at ISO1600 for example (4 stops over base sensitivity), just a slight voltage variation in the order of a few milli-volt will impose large impact on image quality.
Q Images produced by digital camera is naturally recorded in digital form, but it sounds like effort to achieve the required quality is accumulation of “analogue” work.
A Yes, work on analogue portion is critical, without which the later stages cannot be accomplished. It is usually a schedule-critical task and affects on overall performance.
Q Issue of interference between analogue and digital circuits was raised but I can see the importance of skillfully separating the two.
A Separating grounding circuits is one way but it is not simply a matter of separation. Sometimes, good results could be obtained by larger grounding area. This is another area requiring trial and error method.
Merits of 2 channel readout
Q Readout from CCD is 2 channel but it is not a bottleneck for burst rate?
A It is sufficient to obtain the nominal performance of 3fps. With regard to the back end, bus control for example has sufficient room and can accommodate faster sensors. Maximum speed is applied in post-processing, and performance can be maintained with faster sensors.
Q Listening to this, it may have been better to use 4 channel readout for faster signal acquisition, but is 3fps not the limit with 2 channel readout/
A Maximum frame rate via 2 channel readout is indeed limited, and if faster frame rate be pursued, sensor itself becomes a bottleneck. However, 2 ch R/O has merist over 4 ch R/O, namely, lower power consumption and easiness to obtain higher resolution.
Q More specifically?
A As you know, a single layer type CCD has Bayer type filter arrangement (R & G, G & B filters are arranged alternatively). If this would be readout by 4ch, R, Gr, Gb and B are read into separate channel. Concern is over the error between Gr (G filter in red row) and Gb (G filter in blue row). In the case of 4ch R/O, each is read by separate path, creating errors by different paths. This error should be corrected in later processing, but it is not done properly, resolution would have to be lowered, or banding shows up. On the other hand, in 2ch R/O, since one channel reads R & B, and another reads Gr & Gb, Gr and Gb signals can be processed equally in hardware. If the speed is of prime importance, 4ch might be appropriate, but we believe that, from the viewpoint of overall and balanced performance, 2ch would be best.
Q Image processing engine is named “PRIME”.
A Overall imaging performance has been much improved. The key is “image processing engine” that has been renewed and producing very high performance. We thought we would appeal this to users and put an name on it for the first time. We are of course appealing other portions such as A/D converter, DDR2 and other upgrades as well.
Q Reason for using DDR2 memory?
A Because of overwhelming breadth of bus band. When considering fast framing of 10mp images, ordinary memory band cannot respond to the speed without some kind of stress. When we calculated the required memory band in order to clear this problem, DDR2 was found to be most optimum under the current technology. Price is coming down and quality has been improving.
Q I understand that bus speed is now faster. What about clock speed of main CB?
A DDR2 was used in order to increase frame rate, but data bus band is also broadened for faster media writing.
Q By how much?
A More than twice than before. But the writing speed of course depends on performance of media too. You can consider that sufficient band width has been secured.
Q Was it not difficult to develop firmware because of number of new hardware?
A With regard to firmware, it had to be developed from scratch partly because of newly developed PRIME engine. It is a complete different one from those used in other models. In order to improve the “quality’ of firmware, UML (Unified Modeling Language) was utilized. So, we have used new approach/methods not found in this industry before.
Q What is UML?
A It’s an object oriented analysis method. Demand analysis, i.e., evaluation of required functions in this camera was conducted before set about the development of firmware. There only very few manufacturers who introduced UML into assembly.
Q We understand that Pentax determine target users very clearly before starting development of products. What sort of user demography have you targeted by k10D?
A K10D is a higher up model of k100D and it was Pentax’s first attempt to separate lower and upper model, forming a lineup. K100D mainly targeted entry level but with k10D, the target is those who have a good understanding of photography, and love photography. It could be what is called advanced amateur in 40’s to 50’s age bracket.
Q What have you emphasized in targeting advanced amateurs?
A We discussed addition and deletion of each function, suitable for the target users, for example, Auto Picture mode was eliminated and two wheels would be necessary for speedy change of shutter speed and aperture etc. To be an upper model of k100D, 10mp sensor would be suitable, and as resolution increases, SR had to be beefed up. Weather/dust proofing is also demanded by this target user group.
Q Pentax and Samsung are supposed to be cooperating each other. Is any Samsung technology incorporated in K10D?
A We announced the collaboration with SamsungTech last year but the development of k10D commenced before that. Basic developments regarding K10D are all supplied by Pentax. GX-10 as sold in Korea has their own original GUI, that is different from K10D.
Q Any shared parts between K100d and K10D?
A (by Mr.S.Morishita in charge of mechanism/body design)
A portion of mechanism is shared but K10D is mostly a brand new design.
Q K10D body became larger than previous models.
A Pentax cameras have been traditionally compact. But body ended up becoming larger because of larger SR unit and incorporation of weather proofing. We did not put priority in making the body compact, nevertheless, there was a size limit which we tried not to exceed.
It is true that design staff was debating if this size was acceptable when laying out the body design, obviously because Pentax always stuck to the concept of compact size and light weight. However, marketing dep’t responded that performance should not be compromised in order to aim at upper model in lineup. They also said that the size should still be attractive with weather proof incorporated. K10D is indeed largish compared with usual size of our traditional models, but it is NOT big compared with competitions in same price/performance range.
Q Why did SR unit become bigger?
A Magnet and coils were beefed up in order to secure stronger actuation of sensor. As resolution increases from 6mp to 10mp, pixel pitch decreases. This required beefing up of SR unit with some margin.
Q What would be the benefits of beefed up actuator?
A Response and braking accuracy have been improved. Mechanism has been further refined from that used for K100D. Consequently, the correction improved by another 0.5 stop (2~3.5 stops in K100D and 2.5~4 stops in K10D).
Q What’s the degree of weather proofing?
A In SLR, it is rather difficult to apply JIS (Japan Industrial Standard) classification because lenses have to be changed. We set our own in-house standard for weather/dust proofing, anticipating actual environments users might encounter, and exceeded those standards.
In the case of SLR, body is made of so many parts and cannot avoid complicated seams. Al seams had to be sealed, then weather proofing of moving control parts has to be evaluated beginning from the selection of material. For waterproofing, because just one missing or loose sealing will allow water or dust entering into body, we had be extremely careful. It is ultimately a choice of either “doing” it or “not doing” altogether, and there is no in-between. In order to obtain perfect weather/dust proofing, every detail had to be plugged, taking a lot of time and cost. However, we believe we plugged all seams.
Q When opening/closing battery cover, I could feel a tight closure, but not so much on memory card flap.
A For memory card cover, a sealing material is pasted on body side and water/dust tightness is obtained by the cover being pressed on it. Perhaps that’s why you might have felt so. In order to secure the seal tightness, form of cap was so designed that it won’t be loosened by just one action.
Q Hyper programme was resurrected. It was incorporated in *istD but not for *istDS and thereafter.
A Hyper programme was employed first time in Z-1 that was released 15 years ago. It is the same thing in K10D as well.
Q It is hard to describe but very useful function in actual use. This time, exposure modes Sv and Tav have been added, which feels very refreshing.
A In retrospect, installation of hyper Programme on Z-1 was too ahead of time.
But we believe that this exposure mode, which is very intuitive, has finally become suitable and is appreciated in digital era. This function is hard to describe in words and just getting used to is the best way to use this mode.
Q While many makers are now employing penta mirror finder, Pentax are using costly glass prism.
A Prism itself is same as that used for *istD but a brighter screen is used.
Q Default setting for K100D was “bright” but it’s “natural” for k10D.
A We decided on “natural” because of target users being advanced amateurs who we thought would rather prefer “natural” setting. However, by seeing it “bright”, you can obtain the same taste of colour as K100d’s.
Q AF response seems improved. I felt a stronger torque on focusing ring during AF.
A It is probably due to the change of power source. It was changed from AA batteries to a dedicated Li-ion battery. As it can apply 7.2V consistently, AF motor can take advantage of the higher voltage.
Q Any other advantages of changing to Li-Ion battery?
A In using AA batteries, we found varying degrees of quality in offshore made ones, which required quite a bit of built-in margin in designing camera, and could have made a negative impact on response time etc. We believe it was advantageous that we eventually adopted Li-Ion batteries which allowed us designing more tight and precise power supply.
With regard to the change of power source, there has been an argument since beginning of product planning. On one hand, we have been singing the praise on convenience of using AA batteries, and if we abandoned it, we were concerned if users would accept it. On the other hand from the development side, opinions were presented that more advantage could be enjoyed by switching to Li-Ion batteries. In the end, we believe switching to Li-Ion batteries was the right decision.
Q Don’t you have any concerns over third party copies of batteries?
A Pentax have been using proprietary batteries for P&S digicams. We have been constantly watching low quality third party copies, but it is essentially a cat and mouse game. At present, there is no effective measure against poor quality copies. We do not believe it is beneficial to users by raising cost incurring from this measure.
Q So, there is no effective measure for this?
A In Japan, any copies are regarded something “dark”. We of course recommend using our genuine batteries. However, in the U.S. for example, third party copies are much more popular than in Japan. Among copies, of course there are poor quality ones, or even ones using questionable brand/logo design. However, there seems to be little perception that copies are necessarily of poor quality. There is this subtle difference between Japan and there.
Q Battery grip option is available and this looks pretty good.
A Battery grip is often called vertical grip and there has always been a strong demand by users who frequently shoot portraitures. Also, some of overseas users complained that a battery grip of K100D was still a bit too small and we enlarged K10D grip.
Q Batteries are inserted in both body and grip. Which batteries consume first, body or grip?
A It can be set by menu, but basically, larger remaining capacity takes priority. If only for more secure holding, you do not have to insert batteries in grip. But it would be a waste of space, so we created a space for a remote and a card within grip, which are protected from water/dust as grip is also weather proof.
Q Finally, please give us last words from each of you regarding the attractions of K10D from the viewpoint of design/development.
A We adopted a brighter screen which enables easier focusing. Pleae enjoy hyper programme and Sv/Tv modes. In terms of image quality, priority is placed on depiction of detail. It is indeed f=different from 6mp images. Enjoy it.
We believe basic specifications are excellent but please enjoy user-friendly handling too. “Image magnification” in one hand operation, and fine WB adjustment are unique to K10D, not found in competitions.
As a designer for mechanical components, I would like to emphasize beefed up SR and DR etc that are “supporting” features for shooting. Of course, complete weather-proofing, not found in comparable competitions, is also an important feature.
We finally could offer a product which appeals to those who “love photography”. We will continue to offer lens line up with emphasis on image quality.
SECRET WEAPON FOR DUST REMOVAL
Dust removal system by shaking sensor is one of the features of K10D, but there might be cases where dust containing moisture etc would be harder to shake off. Pentax now offer an accessory for removal of such stubborn dust, called “Imagesensor Cleaning kit”. It has urethane rubber tip on plastic stick. You lightly stamp on the surface of low pass filter and transfer dust to sticky sheet. It is actually used in Pentax Service Centres. Mr.Tatamiya himself is using it. ¥4,200
Rumour says that this is called Tatamiya Stick within Pentax.
