I buy the Nikon D300s body as a replacement for the D200, which has shot close to 40,000 frames in 2012. I also get the vertical grip for the camera, and keep that mounted almost all the time. The D300s has shot about 15,000 frames in 2013 and is my day-to-day camera, which performs all photographic duties: indoors, action, location, studio, macro, whatever.
