comment:This lens is noticeably sharper than any of the other lenses i have used on digital. You don't have to view full screen or zoom in to perceive it. The only other one I have that comes close is the Cosina.

Much harder work to focus than the Cosina at macro distances (less dof i guess), but far more versatile (the cosina only gives 1:2 without it's matched 1:1 converter, which I don't have). The A77 peaking mode and focus magnifier really helps with this though.

The limit switch was already loose when I bought it. I suppose this is a risk one takes when buying these old lenses.

Usable sharp at f2.8 but i think f3.5 ideal for portraits. I think the 50mm 1.7 suits my style better on APS-c for this though. I really should try it out on film.

Edit: It's difficult for me to try and describe the subtle differences one sees in images made with this lens on full frame as opposed to APS-c sensor. Simply put, this lens is capable of making beautiful images on either format, but those full frame can be very seductive.
