On the D it takes appr. 1 sec. to focus from close to infinity. That's quite a long run. IMO it's understandable that it takes a while longer to focus, than the FA 1.4/50mm. Regards

Hi all, I've recently bought a 77mm Limited lens - what a black beauty! Today I compared the AF to my other lenses. And I am concerned about AF speed - it is noticeably slower than with FA 50/1.4 and FA 35/2. It is accurate, but slower. Manual focus action is extremely pleasant, tighter than the other two (not as tight as MF lenses but sort of...). I am assuming that one of the reasons can be quite long way from minimum focus distance to infinity (about 1/2 turn) and the other one - that quite tight focus action - more resistance to the AF system. I compared it on two cameras (PZ1 and *ist DS) - with the same results. Can anybody, having the 77, set me at ease? The one I bought was the last one in the store - in case of the return I won't be able to compare it to another one (but my marriage will probably be saved...).
