Ok I've got a seriously dumb question, is there logic behind the Pen naming convention of Olympus m43 cameras? Also, how about Panasonics G naming convention? I'm from the DLSR world of Canon and Nikon. We must be extra slow dummies because both manufactures keep it simple enough for us to understand.....less digits mean higher camera, Canon low numbers are better and Nikon high numbers are better. With all the new camera bodies coming out for both Panasonic and Olympus I'm trying to figure out which is which. Help!
