Perhaps the my biggest grievance with the G7 that I recently acquired to upgrade my GH2 is the loss of a true multi aspect ratio imager. The GH2 shot 4:3 frames at 4608x3456 pixels, 3:2 frames at 4752x3168 pixels and 16:9 frames at 4976x2800 pixels. You did lose about 1MP in each change of the formats, but this was much better than the G7 which has the following ratios: 4592x3448, 4592x3064 and 4592x2584. This is about a loss of 2MP per change of format. In other words, the G7 is simply cropping the 4:3 image. Essentially this means that you should never change your aspect ratio in the camera and make any changes later on in post processing - unless you want to have the viewfinder showing you the 3:2 or 16:9 frames. I had assumed that if one shoots RAW or RAW+JPG you would get the benefits of seeing the preferred aspect ratio but still have the full image available in the RAW file. A quick test of this showed that I am wrong. If you shoot in RAW using any of the reduced aspect ratios, the RAW image in post processing only has what you set the camera for. The pixels outside of the crop are missing. I think this is rather unfortunate and I wish Panasonic had set it up differently. Alas, no micro four thirds camera has had a true multi aspect ratio imager since the GH2 (and perhaps some of the earlier G series). It's too bad as I prefer the 3:2 format over 4:3 and quite frequently shoot 16:9 landscapes.
