While I was experimenting with a 5D Mark III camera body on loan from CPS, I discovered that one of its killer apps is for high dynamic range photography.  No, not its built-in HDR functionality (which is rather underwhelming).  Rather, I am referring to its ability to set autoexposure bracketing for up to seven frames and, when the shutter button is depressed, automatically go into mirror lock-up and rapidly fire each frame in sequence.  The one wrinkle?  If you already have mirror lock-up enabled, this while actually cause a hiccup: it will want you to hit the shutter for each frame.  Canon, please fix this quirk in your next firmware release!

This is much more useful than previous incarnations of autoexposure bracketing: three images really is not enough for HDR photography.  Seven?  I can work with seven!
