I haven’t had much time to test extensively yet and, if I recall correctly, both times I did I was using my flat Trinitron monitor rather than a standard curved one. That being said, I didn’t notice any difference regarding moiré using the MCC compared to my DSLR. With both, I’ve found using a slightly longer lens and soft focus help a lot, together with proper alignment and leveling.
The two big differences I do see right away are:
Genlock reliably removes the overlap bar from the screen image that I generally get with my DSLR. (…Until zooming in a lot, at which point one presumably loses the advantage of matched frame timing when shooting only a small number of lines.)
The MCC footage comes out pretty flat. Post-processing is required to take advantage of its wider dynamic range.
Will report back if I notice anything else (in the process of moving gear around again, so may be a little while before that would happen).
