I just finished shooting some tests with the JVC GY-HM70E. I added a Sigma Circular Polarizer and to my surprise with various good manual white balances I achieved some shots I could not get with the AG-AC8. At full 16x Dynamic zoom the JVC also achieves better color depth - for instance the green in trees - than the AG-AC8. I am more than sure it's because of the 12MP sensor and it being bigger than the other competitors at its price. Also the sound definition from the in-cam mics sound amazing! I'm surprised that this camera hasn't received more hype than the AG-AC8.
