While I am not at all familiar with operating the TG 6 a couple of minor niggles have come to light. The USB port is now down by the hinge of the cover making it harder to access. ( a different plug to the TG 4 ). Erasing images is less easy as you have to access the card set up menu rather than the simple scrolling on the TG 4. Well, that's how it seems to me . The PDF downloaded manual now rather akin to War and Peace.
