just curious, but do you still shoot like this? surely your images are greatly softened via diffraction
Sure difraction reduces some detail, but not having something in focus from too small a DOF reduces it more.

Its a compermise unless you want to start stacking images in post.

At F/32, diffraction reduces more than just "some detail".....

If F/16 isn't enough DOF at 1:1 than you should be focus stacking IMO

(Personally, I can't imagine F/16 not being enough @ 1:1... atleast not with what I do)
