I was at a Dressage show and too some photo's of my Mom riding with my new camera. I was using the canon 50d and canon EFS 55-250mm f/4.5-5.6 IS. The pictures are ice, but when I zoom in they are quite chunky, and not the nest quality. Is this because the camera, lens or settings???? I find Im getting better quality photo's with my point and shoot camera, but need the speed of the DSLR. I thought the canon 50d was good quality, but am now wondering whether I could get any of the photo's printed, let alone enlarged. I will attach a original photo and a cropped. Any advice would be greatly appreciated, since I still have a week to return everything.
