I've seen photos by people who use the native focus stacking in Olympus Micro 4/3 cameras to get awesome shots of insects. I am firmly in the Sony camp but I have been thinking of getting an Olympus body and a lens or two for birds (lens+body is much less than the Sony lens and it can be hand-held) and macro work... Like once I saw focus stacked flower pictures I couldn't be 100% happy w/ the ones I take)
