Re: need to take focus shift into account when fine tuning
In reply to u007, Apr 24, 2012

Yes, I had heard something similar, though not even as wide as f2.2, I think. That's why I raised the question.

Focus shift is often demonstrated in the photozone reviews, and I suppose those lenses with little or no focus shift are more promising.
