K-01 rolling shutter / jello effect / overall video jumpiness

I just picked up a cheap K-01, and I love it other than the video quality. Compared to my old K-x and even a Nex-5n, the video seems especially jumpy during handheld walking shots. I read that CMOS sensors are prone to rolling shutter, but the Nex doesn't seem to have it nearly to the same extent. Has anyone else been disappointed with the K-01 video or experienced similar problems? I really like the look and feel of the K-01, but I might hang on to the Nex or K-x instead.

I think there are more K-01 users in the Pentax SLR forum. I suggest to post there for maybe some answers or comments.

Hi,

Taking video while walking is probably the worst way of shooting,however turning off the shake reduction will help against the jello effect as the sensor tries to compensate for excessive movements it was not designed for. Careful use with shake reduction will produce steady pictures,walking will not. I have the K01,telephoto lenses will produce jello if the camera is not on a tripod,it's just asking too much of the system. Think old fashioned movie,careful and steady. Once you film like this the camera is capable of good results.

Try turning off SR

See how video works when you turn off Shake Reduction.
