I have owned 30 lenses on 4 afma enabled bodies, all of them calibrated properly with Canon and it's only ONE lens that needed no afma and that was one of the three copies of the 50 L, but I write that off as pure luck. All lenses to all bodies should be calibrated through Reikan Focal or other equally good methods. I don't believe that one can own 8 lenses and two bodies and no afma needed. There's a difference between good enough and optimal and everyone is different in how much they see or care about it.
If you only shoot stopped down and never larger than f4 I can understand the statement, but f2.0 and bigger will show it. My 200 f2.0 is calibrated at the same place as my 1d, and it needed +4 and the difference is highly noticeable. It's sharp at 0 also, but mindblowing at +4.
actually i totally agree with you here.
people are different on what they consider 'good enough'. as i mentioned before out of the box i considered my 70-200 f/2.8L IS II to need little or no AFMA. if I hadn't been playing around with AFMA yesterday I'd of considered it needed no adjustment. but just a bit of testing and tweaking showed that actually you can get even better results.
i should really spend time to properly callibrate all my lenses even though i'm more than happy with how they perform now.
viggo it sounds like you send your lenses to a canon service center to be professionally calibrated. do you always send your body along with the lens? and does it always come back performing perfectly?
