my question is ,
does anyone know what Canon "does" when they take both the body and lens for calibration?
I sent in my 24-70II since I noticed that it's not as sharp as my friend's copy (we bought them one week apart). I also mentioned that it's back focusing and that I've tried using AFMA but haven't got it right and would appreciate if that can be looked at too. To my surprise I was told that AFMA "shouldn't be used" except for "special" cases. I said, that I've been doing it all the time with all my bodies and lenses. After I sent a complaint to the person in charge of after sales/ warranty, I got a call saying that the "bad focus" is because I set AFMA and that it's stored in the ROM of the Lens.. My first words "Bull $hit" I couldn't help myself. It was obvious the person talking wasn't technical. I asked, so you mean to tell me that if I set AFMA for the 24-70II on my 1DX those settings are stored on the lens.. Reply.. YES.. .. I explained why this was complete Bull$hit.!! by asking "so that means, I can't use this lens on my other camera bodies.. SILENCE..
Long story short.. I was asked to send my my 1dx which they just "reset" ALL my AFMA settings and they re-flashed the ROM on both the 1dx and 24-70II and asked me to "retry".
I just finished testing using lensalign, (didn't feel like using focal pro). my manual testing resulted in (-4,-4).. Same as what I got with Focal Pro on the first day I got the 24-70II.
Any thoughts.. the CPS guy I spoke to wasn't very helpful.. He kept insisting that I should use the multicontroller/joystick to "SELECT the focus point"
you can imagine my frustration explaining DOF and that the little red square that's on the object tells me where I focused, and that object isn't sharp, hence SOMETHING is wrong. I asked him, do you take photos, he replied yes, I said I'm sorry but you're no photographer.. kinda mean, but I couldn't help it!!!!
Ok Rant over!!!!!!
