    They're a bit pale in real life. Saturation was set to 90% in the grade.

    Samuel, Hi!
    Thank you for the comments, please try to grade the material from both cameras, see what happens under stress.

    Actually, I'm starting to triple guess myself. R, G and B clipping seems to be happening at 235, but there are a few minor excursions above it. A higher contrast clip would help, but I can't find anything meaningful above 235.

    It almost looks like Nikon will allow R, G and B to be full range, but it constrains luma to 0 (or 7.5 for NTSC) to 100 IRE (which I believe would be 16 to 235 digital). The net effect of this being that R, G and B are almost always between 16 and 235.

    But again, a higher contrast clip would be helpful.

    It could just be that neutral profile clipping the levels. I'll shoot something with the standard profile and post it up.

    BTW, here is a blowup of B from the Parade. You can see small dots that show slight excursions above 235.

    For example, if you load a clip into the editor and it shows 0-16 values, this can mean two things:
    * the clip is 0-255
    * the clip is 16-235 and includes the correct metadata, and the editor is expanding that range without telling you
    The only way to know which is which is to look at an original file at a deeper level.

    OK, I'm basically yellow and semi-transparent myself, so I get that
    In any case, an RGB curve increasing contrast also adds saturation, so that 90% number is just part of the equation.

    On the rolling shutter, yeah it's as least as bad as the Nex-5n, it's really the only issue I have with this camera apart from the flimsy flip out screen and no kelvin white balance control. I might have to start praying to the film gods for Nikon to reduce the rolling shutter in the D7100. I don't want to go back to Canon after playing with this toy but the rolling shutter is a problem.

    The +3 sharpness I had set on the bike clip is definitely too much. 0 or +1 with some post sharpening looks much more natural.

    My impression was that the 5N had less rolling shutter issues than my old T2i, so maybe the D5200 is about the same as the T2i?

    I'm going to start a thread to see if people send me files to measure this more accurately on different cameras...

    @Squig Did you have any problems autofocusing with the Sigma 20mm 1.8 on the D5200? I am just curious since I just picked one up and the autofocus is not working?
