I've seen plenty of jello effect, rolling shutter, on video from low end cameras. I've never seen it on a photo before. Especially a photo taken at 1/5000th. I would have thought that was fast enough that there wouldn't jello. Here are some shots I took today. The jello is from handholding it. 500mm lens.

1/8000sec ISO250 f1.9 01 Prime lens, from a vehicle doing about 100km/h.

The sensor in the Q is quite slow. The set exposure time is completely unrelated to how fast the sensor scans. (Slight simplification that is much more accurate than thinking about it like a shutter.)

Use 1/2000 or slower to avoid this problem (on that lens). Any lens with a shutter can avoid it, if you don't ask for a shorter exposure than the shutter can give you. Custom setting 13 "Electronic Shutter" can be set to disable and the camera will not let you set these jello settings any more. (Assuming the lens has a shutter.)

If you adapted lens is on an adapter without a shutter you will always have this problem with it. Use a tripod or get the adapter with the shutter.

Thanks for the explanation drougge. I shouldn't be snapping photos whilst driving but now I'm curious and will test the sensor scan speed of my Nikon J1. Maybe I will get my workmate to drive though.
