>>3655429>for birb photographyJust go for it, it's simply the best format for bird photography unless you're willing to drop 10k+ on lenses for ff. g9 100-400 or 200 f2.8 with 2x teleconverter, will give you plenty of reach for everything you'll ever wish to shoot. Both high end pro lenses. 100-400 is a bit slow, so go with 200 f2.8 instead if you wish to shoot in dusk. It's wise going for them as opposed of mixing lense, since they share same teleconverters, and you get dual is for both lenses. Olympus lenses on Panasonic bodies will only give you body stabilization, same if you do the reverse.
