From all the shots I've seen from this lens, my conclusion follows: it's a ****ty lens to shoot rulers and boxes, and a super lens for people and low light

Apr 24, 2007 06:38 | #62 Manual Focus on the 50L-1.2 has always been fine, and if you shoot rulers and boxes or have time to have your subject say "cheese" it's the lens for you, BUT, IF you want to shoot lowlight candids at a party with AF assist the 35L and 85L are the ones you should own. 1DsIII - 1D IV - 5DS R - IR Rebel -14L II - 35L - 135L - 400L 5.6 - 2 x 580EX II & CP-E3 - 270EX II - 1.4xII - 25mm Ext. - Angle Finder C - Induro/Induro - SkimmerPod II - Toshiba I7 - NEC Spectraview - Pro 9000 II

Here is a link to three composit shots at 2, 4 and 6 feet. http://www.pbase.com/tmr4/distance_test ![]() These show that the backfocus shift is worse close in and at around f/2 to f/2.8. At 2 feet the backfocus shift begins to be compensated for the increasing DOF by f/4 but probably still needs at least f/5.6 to have much DOF in front of the focal plane. Not shown at te link is my test at around 3 feet where the problem is the worse. The backfocus shift is still present at 4 feet though not as evident as closer in. By six feet the backfocus shift has been largely offset by the larger DOF. As others have said, I think the problem is most noticable in controlled testing, but I have encountered it in real-life enough that I avoid f/2 -2.8 when shooting close in. Luckily I bought the lens to shoot wide open in lower light and I've been happy with it there. Here are a couple of shots in the woods that f/1.2 helped get though this particular spot was a bit on the brighter side (these are at @ ISO 100 and I could have bumped up the ISO for this particular series but for some reason didn't). @ 1/320
@ 1/500
All in all this lens is a keeper, but it is a bit frustrating to have even a small issue with such an expensive lens.

My lens has the far focusing problem, or at least it had it- where I'd focus quickly on the corner of someone's glasses to get the eye behind in focus. It was fairly reliable. I retested last night, though, because more of my shots are out of focus, and now the lens doesn't seem to be misbehaving. The only trouble I've had with it is that the focus can be best described as "inconsistent." It's a good lens otherwise. Agreed. "Inconsistent" focusing is how I'd best describe it as well. Had some issues with it this weekend. It missed focus on a couple of shots of my son, while shooting outdoors. My keeper rate is still pretty good though. I'll continue to stand by this lens since it is optically equal to those in the trinity IMO. I just hope Canon comes out with a firmware fix soon, which seems to be the case since it's more apparent when using bodies like the 5D. ~Spaceships Don't Come Equipped With Rear View Mirrors~
