The Nikon D5200 is a very nice all around camera. Unlike the D3200 it features a flip out monitor. It also features the same 39 / 9 focus layout as the D600. I found the Live View Tracking Focus feature a little disappointing (the D600 and D3200 do it very well). It has a built in HDR Feature with quality very similar to the D600. The AWB works very well too. It also features a built in flash, but sadly no commander mode.
