Speaking of the Mosaic AA filter ...
I suggested to David Cubanski that he make an inexpensive device for the 5DM3 similar to his VAF-5D2 AA filter for the 5DM2, but without the optical AA filter -- just the black frame that snugs up to the sensor, with a smaller "aperture" so it crops (hard mattes) the exposed area of the sensor down to a wide aspect ratio such as 1.85:1 or 2.39:1.
Yeah some of us were toying with the idea when magic lantern was just VBR. A couple of brave souls cut out some black card. Doesn't really work for me because I use a mix of prime and anamorphic glass. A magic lantern bit-rate hack is the best option but it could be a while coming, that's if Canon haven't made it hack-proof.
An ALL-I CBR firmware update would be good too.
