Selling Canon 50mm f1.4 to buy...Canon 50mm f1.4
#18
Quote:Another fella who calls 50/1.4 Art unreliable AFing. Huh Strange, I have no big issues with it. Yesterday somebody wanted to buy mine because I told her I don't use it often. At second look, I made like 2/3 of the number of pictures I made with the 35 during the last 5 years, so it's not "under-used". Of course, for me each lens needs AF-adjustment and latest firmware, but I don't have more missed focus with Sigma than with Nikon - which doesn't mean "never a miss", but I could not agree on unreliable focus.

 

I really wonder how this statements are based in reality.

 

But on the other hand, when I rented for a lot of money a 85/1.4 Art, it's AF was so far off that even +20 didn't get it back to work properly. Had to use a combination of dock and camera adjustment. Can't understand why an official importer doens't pay more attention to a correct adjusted lens. I mean, +/- 4 or 5 that's barely noticeable. But that was just a massive lemon.
 

Friend has that lens and I've used it quite a few times. It was worse than AF microadjustment on his 6D. The problem was more like lens failing to stop the AF motor after nailing focus. So it'd both front/back focus quite often, depending on which side the lens was focusing from.

 

Heard the exact same behavior from a few other people as well. Lens was from one of the earlier production batches, so maybe that explains it. 

 

I wouldn't want that lens even if the AF was reliable though. If I'm carrying around a 1kg lens, it's not going to be a 50/1.4. For someone else that might be OK but not for me.
