Originally posted by paranoia23 well if u own a k30 or a k01 ... take 2 clips with the same movement (with and without shake reduction) and compare the jello effect.
jello is caused by rolling shutter ... yes.. but the digital shake reduction in these 2 cams make it worse ... alot.
You seem to be talking about filming, everyone else here is talking about still images. Shake reduction should make jello caused by camera motion less in still images, and should have no effect on jello if it's caused by subject movement.
Jello is probably more often used to talk about filming, but I think that's because it's rarely a problem in still photography. (But focal plane shutters have the same problem, they're just much faster than the Q electronic shutter, and therefore less likely to show it for normal movement speeds.)
