A3 / A3000

A3 / A3000

General Description

This body does not support all features of the KA mount. Although the lens mount features all six contacts, the r1, r2 and r3 contacts are not connected internally. Thus the body can only determine the smallest lens aperture, but not the aperture range. This is probably the reason why the body does not feature aperture indication in the viewfinder.
