Sony's newest addition to its mirrorless lineup expands on its midrange mirrorless line, the NEX-5R. Building on the NEX-5N, the 5R adds some nice upgrades that make it a much nicer camera to use...
There are a few things that increase usability, but I think that the biggest attraction to this camera should be the new phase detection autofocus. This method has been adopted by a few other camera manufacturers more recently as it proves to provide some of the best autofocus results out there. The addition of this system on the NEX-5R should really make it an easier and faster camera to use with less hunting.
Set between the NEX-3 and NEX-7 models, the new 5R isn't quite as robust as its big brother, but a new control dial at the back adds a level of use that was much needed on the camera, and serves a very similar function to Nikon's DSLR control dials that control aperture and shutter speed. Additionally, a new dedicated function button has been added while the on/off switch has been moved around the shutter button, again more akin to the Nikon/Canon DSLR-style switches.
Finally, the 5R's built-in WIFI and new compatibility with Sony camera applications open doorways to new possibilities such as uploading directly to Facebook (or potentially any social networking site in the future).
