Slipping into Sony's compact Alpha interchangeable-lens camera line between the not-much-cheaper NEX-C3 and seriously equipped but substantially more expensive NEX-7, the Sony Alpha NEX-5N's solid quality, performance, and features offer surprisingly good value for the money.
The NEX-5N is capable of shooting some very nice photos, and has an excellent noise profile for its price class. JPEGs look clean and artifact-free as high as ISO 400, with a little smearing from noise suppression starting to appear at ISO 800. But even as high as ISO 1600 detail on the main subject looks pretty clean (artifacts do appear on peripheral areas). It will be interesting to see how well the raw version stands up and if there's some latitude to be gained there once the codec is available. Overall, the camera's noise profile and images look very much like the C3's although the choices in the program exposure mode seem to be 1/3-stop darker. But there was even sufficient dynamic range to recover detail on the horribly blown out flash photos produced by the optional bundled flash. The colors are good--accurate and not overly saturated--and it doesn't blow out detail on saturated reds.
If I sound hesitant to call the photos excellent, that's because I think the camera takes a hit on sharpness. Perhaps the kit lens could use some better coatings to improve clarity and brightness, though I shot with the 18-200mm lens as well (which performed better).
Video looks very good, with bright, saturated colors, relatively sharp edges, and with no rolling shutter or moiré, rock solid in 60p. You can see some compression artifacts on especially busy scenes (like splashing water in front of trees or bushes) which may affect editing--it looks fine played back on a display or large-screen TV--but detail and dynamic range are better than many of Sony's similarly priced camcorders. The autofocus works quickly and quietly while shooting video as well.
There have also been reports on the Web about a mystery clicking noise and overheating potential. I did hear the clicking, but unlike others I could hear it when I moved the camera near my ear--it sounds like one of the controls is just perceptibly loose on the inside, plus it's quite easy to hit them while you're gripping the camera in your right hand. (Update 9/19/11--Sony has confirmed the phenomenon exists, but has no further information about how many units have been affected, its cause or possible cure.) As for overheating, I shot up to the full possible clip length indoors--for legal reasons, it (like all cameras) maxes out at just under 30 minutes--but the camera felt quite warm when it stopped, so in hotter conditions it could very well overheat at shorter intervals. How important that is to you depends upon what you plan to shoot.

Performance was solid but a bit disappointing given how fast its competitors are getting (in the chart, the E-P3 is a proxy for the E-PL3, which is supposed to have similar performance but which we haven't yet tested). It takes 1.2 seconds to power on and shoot, which isn't bad but is relatively slow. For single shots it does match competitors, with a time of 0.3 second to focus and shoot in good light and 0.6 second in poorer conditions. The camera stumbles on image processing, though, taking about a second for two sequential shots, increasing a bit to 1.3 seconds with the flash. And it gets noticeably slower at high ISO sensitivities, briefly throwing up a "processing..." message. It can burst at about 3.3fps, which is sufficient for occasionally shooting kids and pets, as long as they're not moving too fast.
