Summary: I've been using this camera a while and my opinion regarding its quality looks like this: Its design is very interesting. IT feels very handy. But that's about all with the pros. The cons are as follows: it has no flash and this is a big disadvantage. The battery is not so good (it will drain very fast). The quality of the pictures is mediocre.
Summary: After carrying this camera around for a couple months and shooting thousands of photos, I've come to the conclusion that this camera was a complete waste of money. I wanted DSLR quality in a compact profile, but this camera isn't even close to DSLR quality, forget the sensor size. If you're just want a better point and shoot, this camera might work for you--except that it's a lot bigger and more expensive than a high quality point and shoot.
Summary: I chose the Nex based on the stellar Amazon reviews. Unlike many, I am coming from a Canon dslr, but I'm by no means a pro, I just like great pictures with nice depth of field. Most of my photos are of my kids, so a lot of close ups and vacation shots, both in bright light and indoors. There are a few areas where the Nex is completely unacceptable. The auto focus is awful.
Summary: I have a pocket point-and-shoot and wanted to upgrade. My wife and I use zoom on about half our shots. I saw the NEX-5 (with pancake lens) had digital zoom and realize you loose resolution when you digitally zoom. But I figured I'd get much better shots (than my point-and-shoot) when not zooming and shots about equal to my point-and-shoot when I used full digital zoom.
Summary: As the title states; Sony NEX5NKB compact system camera (16.1 megapixel). That's what I expected to get. Instead, I got the NEX5 (14.2 megapixel). Don't understand why you would do such a thing. Safely say I won't be buying from you again.
Summary: ----Update on 2nd July 2013---- I lowered the stars from four to two. I find the build quality of SONY is becoming worse and worse. I have experienced so many problems with SONY cameras and lenses. The NEX-5N has the famous "click" issue when doing video, I got that one returned to Amazon. Then I bought another one but it showed a "Camera Error" after each shutter triggered. Now the same problem just comes to the NEX-5R.
Summary: Great service from Amazon; great camera yet still sending out 'clickers'. I ordered a black one and it clicks really loudly when using the movie function; not sure if it is worth taking the risk and ordering another one?
Summary: I've just taken delivery of this camera and within 10 minutes, I've submitted a return to Amazon for a refund. I took it out of the box and there is something rattling internally. A quick Google search reveals this is a common fault; possibly in one specific manufacturing batch but it's unacceptable. Sony should be ashamed of themselves for letting this problem through.
