Testing Canon 5DmkIII RAW with Anamorphics. I can shoot 1920x1280 (3:2) and 1920x1080 (16:9) however it's how the footage looks after stretching it to the correct ratio. However, both have to be trimmed at the edges to fit 1:2.40 ratio, just that 3:2 is less than 16:9. I guess for 85mm or below that vignettes, 1920x1080 makes sense because I can trim out the vignette edges. But I lose a lot of resolution if I do that. Also I can shoot with a GH3 and do the same thing. If anything I get greater fidelity with the image because of shooting RAW.
