True, and smart adapters further broaden the appeal of that version. Still, better late than never! Having auto-aperture significantly improves the macro shooter's experience. And this will be doubly true with the improved viewfinder in the K-New...
BTW, I'm not sure, but if I understand correctly, I believe they are also releasing today a
second EF version with clickless manual aperture, for video-centric work.
