The Nikon D7000 Digital SLR Camera is a good all-around system for a variety of shooting situations. It is fast enough for most events, can shoot HD 1080p video, and sports dual SD card slots for easy backup. The 39 point AF system tracks subjects easily and the built-in flash acts as an optical commander for off-camera Speedlights, like the SB-910. Full frame and crop frame format F mount lenses are compatible with this camera. It is designed for crop frame (DX) format lenses. When using full frame (FX) format lenses, your effective focal length is multiplied by 1.5x. This camera is ideal for weddings, candids, and light documentary filmmaking work.
