The Nikon D5100 is really a solid camera with outstanding photo and video quality, but relatively slow performance tarnishes its draw for me. Nikon fixes that within the D5200 with the same new autofocus and metering systems that debuted in the D600, plus an up-to-date bigger-end viewfinder, and the result is just a noticeably better shooting experience that helps it be a great choice for several-around family and vacation photography.
