Originally posted by emr Can anyone say from that picture whether there's any chance of AF?
Yes, there is. I don't agree with previous comments.
The locations for electrical mount contacts (not SDM) and the AF screw are holes.
I.e., the picture shows an incomplete adapter, probably a prototype.
Leaving a hole in the prototype where the AF screw is located makes no sense if the final product doesn't support AF. Missing AF should mean a blank metal ring. To me, it looks like a prototype of a crippled KAF2 mount adapter.
Also, I learn from early comments that the Samsung lenses are not ultra sonic. They may well be screw drive. And if this is so, screw drive AF may be as esay as an 1:1 coupling.
However, I agree that there seems to be no SDM support. As for screw drive support, I remain undecided.
