Re: Using global-default AF Tune as +/- 20 workaround

Interesting.

anyhow I tried it on the 85/1.4 and this method, FoCal and hand adjustment based on photos with 3d subject (made by books) came very close. a difference of  1 in the normal AF scale.

the nice thing about your method is that it can be used in the field when distances or light messes up the tuning.
