6:4.5 and 8:10 crop modes.

Currently the 5dsr has an overlay for 1.6x and 1.3x but it would be really nice to have 1:1 and several other crop modes.

I didn't think much of them at first but load the raws into Lightroom and the crop setting goes with it and the ovf has an overlay to assist with framing too. Great for those moving from a medium format sensor and who don't like 2:3 dimensions.
