The Bottom Line For the money, the Canon EOS Rebel T3i is a great choice for dSLR videographers--though the cheaper T2i can still suffice if you don't need the articulated LCD--and it's a solid choice for creative still shooters. But though the image quality and general shooting performance are top-notch, if you're upgrading to capture sports, kids, or pets, the T3i may not be able to keep up. A very good entry-level dSLR, the Nikon D3100 delivers excellent photo quality in a body that's streamlined for experienced photographers, but relatively unintimidating for the less advanced. Its only weakness is performance; though solid, it nevertheless lags behind the competition. Though it doesn't rank first based on any individual aspect of the camera, the Nikon D5100 delivers a solid combination of image quality, performance, features, and design that puts it out in front if you're looking for a well-rounded option under $1,000.
