I have a Canon MPE 65 Macro Lens. Because it is designed for extreme closeups the depth of field is very narrow.. Focus stacking is necessary to get a whole insect or flower blossom in focus. Automatic in camera focus stacking is a feature of the new mirror less Canon RP. However, when I search it on the net, I am told that it only works with about ten Canon branded EOS lenses and the MPE 65 is not one of them. I would appreciate hearing from an RP owner who has tried the focus stacking feature.
