I need opinion. I am currently in the process of choosing of camera. After reviewing, I narrow it to Olympus epm1 and Canon G16. Does anyone have this camera? I usually dive in tropical, shoot some macro (nudis) and wide angle (seldom though). My previous camera is canon S100, with single strobe. I am also looking for good life cycle of this camera (option of upgrading using macro add on lens (subsee +10, +5)) . Thank you
