The video community is running wild with all types of samples from the new Magic Lantern hack that enables RAW output from the Canon 5D Mark III (and soon other cams). The guys over there are doing some amazing work, so make sure you stop by and donate to get this project moving faster. The 11 stops of dynamic range pulled from a full frame sensor camera is an amazing combination to have.
I'm guessing once the ML menus have been refined and the workflow to process the RAW images becomes easier, this will create a second wave demand on the 5D Mark III. If you're looking for one, the Canon 5D Mark III currently retails for $3400+ (no current rebates), so as a reminder there are still deals available for Brand New, USA Warranty, Canon 5D Mark III cameras at below $2890 (check here).
