Silly question about aspect ratio - do you shoot 4:3 or 3:2?

With your camera it's best to shoot 4:3 and then crop.

With the GH1 & 2 or any other camera with a multi-aspect-ratio sensor it makes sense to shoot 3:2 as it will use a larger horizontal part of the sensor (and a bit smaller vertical part) than when shooting 4:3. But on the GH3 and many other cameras the sensor really only does 4:3 and other aspect ratios mean cropping from that image. So on your camera you do not gain width by shooting 3:2 but you do lose height.

There is also a difference in what cameras save in a RAW image file. The cropping done by setting the aspect ratio may delete the unused pixels from the RAW file or may leave them in. When the unused data is left in the image (as with Olympus cameras) you could uncrop the image in post-processing if your RAW convertor allows it. (ACR and Lightroom for instance can do that with cameras introduced after the E-M5 (not including the E-M5 itself despite the data being in the files).
