I tried video with a EM5 but I was not happy so I bought a GH-3. Now I am happy. My original use was as an unmanned static camera but I really like the form factor so I have been trying it as a candid roving camera......not bad. My favorite lenses are all Olympus which means there is no stabilization when mounted on the GH-4. I am looking for some feedback on using the Panasonic 12-35 for video. Your thoughts?
