Focus Trim on Phase One XF
Having just installed Update #4, I'm now re-doing the focus trim for all my lenses. I'd be interested in any views on the focal length I should use for the SK40-80 zoom.
One logic says that trimming at the longest focal length (80) is best because any slight shifts with zooming would be covered by the extra DOF at wider angles. Another says to use 60mm, right in the middle of the range, as the best compromise.
There are some great techies on this forum so I seek your better educated advice!
