Has anybody used LensAlign Pro lens & Camera calibrating System? Would appreciate critiques and comments- thanks in advance. I have Canon 20D & 50D and the following L lenses:F4 17-40, F4 70- 200 IS, F2 135 and F2.8 200 primes.
Robert ... I have a 5DII and 50D. My 50D is much more difficult to MA than the 5DII because of the greater DOF you are typically working with. I haven't looked at the LensAlign for a few months, but the last time I looked at it the ruler was really to short to work at recommended distances on a 50D. You can check this yourself by computing the DOF for your lenses at recommended calibration distances (at planned focal length and aperture). CLICK HERE for the system and approach I use (plus there is a table of recommended calibration distances if you are unfamiliar with Canon's recommendation in this area).
