I am looking at the new Mirrorless cameras, the Sony NEX-C3 was just released, but the older NEX-5 is selling for the same price. Video-wise the difference is that the newer lower model NEX-C3 does 720p in mp4 format. The mid-range NEX-5 does full 1080i AVCHD. Both of these cameras will be great for me to play with, but am unsure of the problems I will face editing and storing AVCHD format. MP4 is handled incredibly simply with iphoto and imovie support. I have downloaded sample clips from dpreview.com and both cameras produce very similar quality.
