Linear Operation of the Diaphragm Actuator
The least-noticeable change is in the movement of the diaphragm actuator. In the original K-mount its displacement is proportional to the diameter of the diaphragm opening. In the KA mount, it is proportional to the area of the diaphragm opening, and thus to the selected f-stop. This leads to an identical stop-displacement between any two consecutive f-stops, and thus greatly simplifies the operation of the body in the Tv and P operating modes. All KA lenses have the same stop-displacement.

The diaphragm actuator’s change in operation does not lead to any incompatibilities with older camera bodies. This is because the diaphragm release of these bodies always moves all the way up, and allows unrestricted travel of the lens’ diaphragm actuator.

I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhauser gate. All those moments will be lost in time, like tears in rain. Time to die.

Przypuśćmy, że skok popychacza to 10mm

rj1307, popychacz działa relatywnie do maksymalnego otworu względnego danego obiektywu. Inaczej mówiąc, przymyka przysłonę o określoną liczbę EV.
