For my professional work, I use the Canon 5D Mark III, 6D, and 1D Mark IV. For non-pro, I use the Nikon D750 and D810. Each camera has its strengths and weakness over the others, but the one DSLR body that reigns supreme is the D750. It is the best all-around DSLR.
Purchased this just over a year ago from NewEgg; What makes this the best Nikon DSLR available: high ISO performance, built-in Wifi with avail Nikon device apps for remote control and photo access, swivel LCD screen, and fast focus.
Wish it had built-in GPS for geo-tagging
