Never too late for... a stupid question
Underwater, a lens minimum focusing distance will increase or decrease?
Specific case: lumix 12-35mm behind Nauticam 6" dome port (its port according to Nauticam).
Sunday I made several nearly macro shots at 35mm with the subject very near. The camera indicated me focus acquired (single area pointed exactly on subject, AE lock, green square). Even on the boat, on GH4 display, images seemed gorgeous but at home on my PC i realized they were completely off focus. (I ate the dome cover).
