The diameter of the exit pupil (/lens) is not the same as the image circle !
Image circle is the circular picture the lens is forming on the plane of the sensor.
My fa 28 mm lens have a much smaller lens at the back compared with my fa 50 mm, and still is a full frame lens. (Though light rays will fall at a greater angle onto the sides of the sensor)

If Pentax/Ricoh ever is going to replace K01, I think they should look at this one.
Make it K.mount with circular protrusion (correct word?) in place of the K-adaptor on this camera.
Maybe use this ring for aperture control or other.
Slightly larger/deeper grip could probably be used without destroying the impression of sleek/thin camera!?
