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.
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.
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.
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.
Summary: Be forewarned that if you plan to use this camera in AVCHD video mode in a warm environment, it WILL overheat and shut down. Google "NEX 5 overheat". By "warm" I mean just about any summer day, outdoors, for longer than about 10-15 minutes. Good thing my car or phone doesn't do this.
Summary: The quality of this digital camer is simple excellent but without the viewfinder you can't easly make photos outside especially with the full sunny day, why.... it is very hard to focus on a thing you want by using the screen. Can't recommend it.
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.
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? :(
