I mean its good...much better than before, but notice the jelly effect? Was hoping it'd be gone by now...maybe the d400 will have it corrected...

Rolling shutter is a by product of using a CMOS sensor. As long as they keep using that type of sensor the jello effect will still be there. Software can minimize it but it can't get rid of it completely.

I didnt see the jelly roll. But hey i could be wrong. Were you using AF during this shoot?

The jello effect is present in that video, you notice it when the camera swings or moves side to side.

ok i did notice something. but it was at about 20 seconds in and the camera was trying to AF on the bicycler. in fact, i think the jello effect is actually when the camera is trying to AF. id like to see a simiar video with the camera on a tripod.

Rolling shutter (as opposed to global shutter) is how (most) CMOS sensors work. Rolling shutter need not be a problem. Slow line-read speeds is what allows a rolling shutter to create the jello effect.There is no reason a CMOS sensor must produce visible artifacts, line-read speeds are increasing every generation. Also there are CMOS sensors out there which don't use rolling shutter.
TL;DR? It isn't as simple as blaming CMOS.

@Drab - I dont see the jello effect unless the camera is trying to focus. Thats just me. If you see it, please point out the times.
