| MA with zoom lenses |
I don't understand MA with zoom lenses. I'm working on my 70-200mm right now with a Canon EOS 1D Mark III.
I find I need +12 when at 200mm but no MA when at 70mm.
What does this mean?
(The same holds true for my 24-70mm....MA varies by focal length).
*NOTE: I've done this manually as seen in the Canon manual, and again with FoCal.
