OK, so I have a 1DMK3 and a 7D. i got my new (Super old) 300 2.8 NON IS in today. it needed calibration pretty bad. I use FOCAL, it has served me pretty darn well in the past and has zeroed in my lenses.
So i started with my 7D and it said it needed +17... no biggie.
But when I hooked up my 1DMK3, it seems that they have lost functionality with their newer software. it wouldn't let me do anything. So my question is, it the +17 just for the lens? so I can put +17 on the 1DMK3 and call it a day? or is calibration determined on lens+body combo?
