I have been configuring afma settings for my lenses these past few days. A bit of a tedious job, especially because I had not done this yet for any of my lenses and so had to do it for all of them. I think it will pay of tough, especially for my 50mm f/1.4
I did (or tried to do) the last one this evening: EF 70-200mm f/4 IS L + EF 2x iii. On the wide end, the scale on the DataColor SpyderLensCal target was always entirely in focus, for any AFMA setting ranging between +3 and +9. While I can obviously live with this, I find it a bit strange that the AFMA setting has so little (or even no?) effect. On the tele end, there is generally a small amount of front focus, and again the AFMA setting seems to have little or no effect (at least over the range +3 to +11 which I tested).
Has anybody else had a similar experience? Is there a limitation to AFMA for f/8 max aperture lens/teleconverter combinations?
And another small question on the side: does AFMA have any effect on Servo AF? In DPP, the AFMA setting is listed for photos taken in One Shot AF mode, but not for photos taken in Servo AF mode.
Thanks in advance for your feedback!
