The sdQH, and I presume also the other Quattro cameras, do not have video. I haven't missed it.

Greater dynamic range, with which comes usable results at higher ISO settings, would be a welcome improvement. It's one of the best things about the fp. I am sure Sigma are working hard on it.

My sd Quattro has to have some sort of functional video to support the EVF and rear LCD. The fact that video recording is not done seems to me to not matter. The basic video functionality is there in the Quattro sensors.

Any full frame Foveon would need video to work in a mirrorless body, in my opinion.

Barely relevant is this paper by Hubel:


Of particular interest is Fig. 3 (B) showing the use of the optimal green layer for video luminance as opposed to the Quattro's use of the top layer.
