Nikon WU-1a wireless mobile adapter for D3200 review
 

In the world of DSLR shooting, you can certainly catch one's attention by mentioning one of two things: a wireless display, or a remote trigger setup. Neither of these are exactly fresh concepts, but Nikon has chosen a curious beast to highlight one of its most promising accessories to date. The $60 WU-1a Wireless Mobile Adapter primarily allows two things to happen. First, it enables your Android phone or tablet (and soon, iOS device) to act as a wireless display. You shoot an image, and within seconds, that image is ready for your ogling on a far larger display than the 3-incher found on the D3200's backside. For those looking for a far better way to review each shot without pulling out the laptop, this is it.
