I put together sample footage from the Panasonic GH3. Before purchasing the camera it was difficult for me to find a good review that was cinematic or had cinematic quality. This camera really is worth $900. So inexpensive but packs a tremendous punch. One of the only downside (excluding moire and aliasing) is the crop factor when using non MFT canon and adapted nikon glass. The Vello MFT adapter works like very well, but I am really looking into purchasing a speed-booster.
I just recently purchased the Panasonic GH3 as a B Cam. So far it stands up really nicely with the 5D Mkiii. The FullHD 60p on the GH3 is stunning. Especially for the price. Looking forward to the shoot tomorrow.
