Hello, before people start to burn me, please let me explain. I am an enthusiasm/occansionally pro photographer (i.e, shoot photography as a passion, and get pay about 8 times a year). A long time Nikon user, recently convert to M43. Originally I have the D700 and D7000, however I change my D7000 for an OMD, and loving the little Olympus. With the OMD, I understand that it couldn't really Continue focus as well as the D7000, so I use it mainly my personal passion photography side, it is small, with great IQ and a pleasure to carry and use. I have been mainly using this camera for about 4 months now. So come to my D700, I have this with 24-70 2.8 and 70-200 2.8 VR2, which I put as side to use to the paid Sport Photography job (mainly during the summer). I recently got the set out (a friend ask if I would be their wedding photography), and realise how heavy the whole thing is. I haven't used the GH3 so can't say much about, I understand that DSLR are still much better with Continue Focus, just wondering where with my limited used is it worth keep the D700 with the 2 lenses, or is the GH3 good enough to replace the D700 for those occansionally Sport Photography jobs? Nikon D700 vs Panasonic GH3? D700 - Full frame with great Continue Focus GH3 - Seem to be much smaller and light Nikon 24-70 vs Panasonic 12-35? Nikon 70-200 VR2 vs Panasonic 35-100? Anyway help, advice would be most appreciated.
