Originally posted by Kunzite I'm not upset. And I'm supportive of a revised 50mm macro. I don't believe it will happen, but even KAF4-compatible extension tubes would be nice.
And while they are at it, I'd love to see a KAF4 reversing ring.
The product would have: 1) the reversing ring (an adapter between KAF4 mount to filter ring screw threads) that attaches the reversed lens to the camera, 2) a small mount ring you attach to the back of the lens with KAF4 & mount ring contacts, and 3) a short curly cable to communicate the KAF4 signals and power between the camera mount and the reversed lens.
A full-function KAF4 reversing ring would enable control of the aperture and AF motor of the reversed lens.
