Let me resolve your dilemma. Send the lenses to me! But, yes, I think they work just fine. I occasionally use my Nikkor AI or AIS 24, 50, and 105 lenses and love the manual focus workflow. The manual focus itself seems to provide me with a much better feel for depth of field, because the focus is MUCH slower than AF, and you SEE what's happening as you turn the focus wheel rather than having it all happen in an instant. I also like selecting the aperture manually. Having come from Nikon manual focus film cameras, it all just feels so much more natural.
