Reikan FoCal - Automatic AF Micro adjustment software

[Bill_in_WA]

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.

The camera knows you have the TC on, as long as it is a Canon TC.
I always thought the same when using the TC with zoom lenses that the TC was to "soft". The 70-200mm II might be close to performing acceptable with the TC on but I have never had a need for it, really I have only found the 1.4x acceptable on the super telephotos and primes. Really it all depends on what you think is "acceptable" and my opinion may not match others.

Thanks for the information... Yes, it is a Canon TC and I had a "Senior Moment" on the 70-200 issue... What I shoul have written in is the 100-400. As I gain more knowledge I am not so sure that taking the 100-400 and screwing on a TC might not be presenting a lot of variables in AF... maybe a bit too many. We'll see what happens... it should be interesting. Just ordered the FoCal Pro so I'm sure I will be back on asking more questions.

Your 100-400 will not focus with the 1.4x TC attached, so I do not think FoCal will help you with that combo.
