...from a guy relatively new to m4/3. 1) Is there a short explanation somewhere of what the differences are between all the Oly bodies? The Panasonic stuff I think I figured out, but the Oly nomenclature has me confused as hell. What do the "M" and "L" variants mean, and how have things changed from 1 to 2 to 3 series?? Do all the bodies have IBIS? Searching here and on Google hasn't helped. 2) Do you find that the IBIS helps noticeably with adapted telephoto lenses? I bought a GF1, which I like a lot, but then got adapters and a bunch of alt glass. Handholding a 135mm in dimmer light is a little tough without stabilization, so I'm wondering if an Oly body would make sense for me. Thanks.
