Have anyone noticed Rolling Shutter Effect in d5100?? and is it only visible in the videos, and will not affect the stills?

Haven't tested it but I would expect it to be present. See
en.wikipedia.org/wiki/Rolling_shutter .
The D5100 does have a CMOS sensor...

thanks, saw that.
but does it affect the stills also??

Only a problem with video, won't effect your stills.

If you use it for video, there is actually an easy "fix" for it if you own an Apple computer with the newest version of iMovie.

While not perfect, it eliminates the worst of it, and makes the videos with fast movement very usable.

then this problem is only for videos, and the videos with no very fast movement will not cause a problem.

Correct. The problem gets worse with a high MM lens (200mm)...and also with lower aperture (below f2.8)

I have a 500mm mirror lens, and even on a tripod, there is some wibble-wobble just from wind.

I wondered if the effect on the hubcaps of this car is due to rolling shutter. Opinions?
Things I couldn't do before

rolling shutr effcts cannt be seen in still images, as said by amccune.
Your photo have a low 1/10sec shuttr speed. Thats the problem i think..

Yeah, your exif data:

...shows that it was 1/10th of a second. 1/1000th of a second, and it would look like it is standing still. In fact, looking at your EXIF data again, you had it in "shutter priority mode" (S) which means you had it set this way, either intentionally, or unintentionally. Either way, you will get this effect at a low shutter rate.

Try it in bulb mode, at night and hold the shutter down for 10 or 15 seconds as the cars go by - you get some amazing results (use a tripod...)

The slow shutter speed was intentional. I was experimenting with it. I do plan to go out and get some night shots of various kinds sometime.

I don't consider the visual effect of the hubcap a "problem" in this photo, but a curiosity. What is it about the long exposure time that caused the hubcap to produce that regular, repeating pattern, as opposed to a smooth blur like most of the other moving parts?

Just thinking about it now, I think I've answered my own question: I think what we're seeing is several overlapping cycloids being traced out by the brighter visible points on the hubcap.
