Like many others in this thread I have been contemplaating the calibration of my 7D and 5D MKII to my 6 Canon lenses. While both LensAlign and SpyderLensCal have performed well for many people I was hoping that there might be something better on the horizon. Once again I wrote to Bryan and, once again, he had a great suggestion... FoCal... and this thread.
Have read the theory of FoCal until my eyes glazed over and have found the information on the site and in this thread very illuminating. One question I did have came to mind when I read the posting from John relative to doing a calibration with a 1.4X TC attached to his 70/200. I am going to both admit and show my ignorance by asking how, exactly, would the camera AFMA go about identifying a lens with a TC on it and how would it be listed/registered within the index of AFMA lens in the camera?
I have long thought that both my 100-400 and 70/200 have been a bit soft with the TC (and the 100-400 by itself). FoCal may just be woth its weight in gold to a "non-techie" "sort-of techie" like myself. Thanks for any help or suggestions any of you may make.
