Just Posted: Nikon D5200 in-hand preview. We've been able to spend some time with Nikon's latest mass-market DSLR - the 24MP D5200. At first glance it's nearly indistinguishable from its predecessor, the D5100, but beyond the sensor, it also gains the 39-point AF system and 2,016 pixel metering sensor from the D7000. This represents a significant step up for this class of DSLR. It also has the option to join the 'connected camera' set, with the option of a clip-on Wi-Fi unit. Is this enough to keep the D5200 relevant amongst its smaller mirrorless rivals?
