The latest Nikon D3200 was being announced a few month back. This DSLR is target to replace its predecessor, Nikon D3100. A few key upgrades has been made to the D32oo model such as the resolution for it is bigger about ten times than D3100. Other than that the processor for D3200 has been upgraded to the Expeed 3, and while the D3200 retains its predecessor’s 3in fixed screen, the display resolution is increased to 921k pixels.
The Nikon D3200 looks remarkably similar to the D3100 it replaces, but there are some differences I’ll note in a moment. The body with card and battery weighs 505g and measures 125 x 96 x 76.5mm, that’s the same weight as the D3100 and just 2mm deeper. At 527g with battery and card, the EOS T2i / 550D is a tiny bit heavier and measures 128.8 x 97.3 x 62, but isn’t 14.5mm slimmer as these dimensions suggest, they are more or less exactly the same depth, Canon and Nikon just do their measuring at different points. The Nikkor AF-S 18-55mm kit lens looks a little bulkier than the Canon EF-S 18-55mm, but in fact is only 2mm wider in diameter and weighs 5g more. So in terms of operational size and weight there’s really not much in it.
The D3200 is a comfortable camera to hold, it has a slightly deeper, more contoured grip than the T2i / 550D and with your palm on the base of the body the lens zoom ring is a more natural fit for your left hand. The top plate looks similar to the D3100, but there are some significant differences. The Exposure compensation and info button (which toggles the rear info display) have been joined by a dedicated movie record button which replaces the combined Live view/movie recording Lever/button on the rear panel of its predecessor. And the mode dial loses its continuous shooting lever, but otherwise looks the same and has the same positions as the earlier model.
