I am looking at the 85 1.8/85 1.4 and the 50 1.8/50 1.4, both lens were tested on a d80. I went to B&H today to handle them at the counter. The 85 1.8 was slower and took longer to lock focus, did they drop it in the store or is this typical of these lens? The 50 1.4 was much faster then the 85 1.8 to lock focus. I did not test the 1.8 I am wondering if anyone knows if there is any difference to how quickly these lens focus on a subject? Is one slower then the other? Is there a greater degree of focus accuracy? I have read about the other differences but nothing in this area, was this just a messed up store display sample?
