re: #3 CuriousLurker

I may have mentioned this but lens techs tell me the sharpest any lens can possibly be is wide open and at minimum distance. And coatings matter. And we rarely want softish in macro right? What I inferred from that is when the depth is too shallow for the shot you want, stack rather than narrow the aperture. And Lightroom has made that easier than it was. I have not yet take macro that far, I have this pesky inclination to stay in camera.
