Re: Suggested feature to fix focus shift

There is an advantage to focus wide open.

I was proposing to allow a configuration per lens (remember the micro adjustments in DSLRs which are per lens adjustments) where the user will set the focal range where to focus stop down and the limit for the stop down.

For ex the focus shift doesn't happen on many fast zoom lenses on the wider portion of the zoom.  It also changes only in the first 1-2 stops from the wider aperture.  So for ex:

A picture taken at 70mm F4-F22 should focus with F4 but a picture taken at 70mm F2.8-3.2 should focus at the required aperture.
