I have had a D5100 for almost a year now. Loved the camerea, takes awesome pictures. Recently I have been having a problem with the camerea. When I take a picture, I take the picture but before I finish the picture in side does a side shuffle. (It jumps) sometimes causing a picture to be blurred. I let someone barrow my camerea to take pictures and then this started happening. It seems a setting was messed with but I can't figure it out.
