Tried the focus stacking feature after firmware update in my GX85. In camera, there is 1) an auto option and 2) a range option where the user selects which areas to be merged (and which areas to be ignored) while focus stacking. Posting 3 stacked images of Holy Basil (about 5 mm long). All from same mp4 sequence. Tripod used; Natural light from one side; touch shutter release. No post processing except cropping. GX 85 + Pana 45/2.8 macro Pl comment on the in-camera processing quality as seen from a and b using 'c' as reference (164 frames stacked using zerene stacker pyramid) Appruk.
