I am a complete newbie to the micro 4/3 world. I have looked over a lot of the forums here - lots of really good stuff. I shoot birds, wildlife, and grandkids. Tired of carrying around Canon 7DII, 100-400 II, 400 f4 DO II, and a CF tripod. The things I like about my present kit is the IQ and the fast focusing speed of both my lenses. What I dislike about it is the weight and bulk. I am especially interested in these two lenses - the Panasonic 100-400 and the Olympus 300 f4 and its teleconverter. I have no idea which camera body would suit my needs. My initial inclination is to go with either the Olympus OM-D E-M1 or the Panasonic GH4. I have no interest in the video capabilities of either body. Both Olympus and Panasonic seem to have numerous different camera bodies. I would appreciate any suggestions, comments, etc. about which camera body would do best considering my interests and the two lenses I have mentioned above. Thanks in advance.
