The online reviews don't give this lens a lot of credit, but I find in the real world it does rather well. It's not highest resolving lens, but distortion is very well controlled (unlike the standard kit lens) and it gives a unique perspective - one that seems to match the APS-C sensor size well. Except for the dog pic, these are all shot in JPEG with the toy filter on the Nex-3; brightness, contrast, and unsharp mask adjustments in Photoshop.
I'm kinda happy I've bought the 2 lens kit, although I had to wait 6 weeks for it 'cos it wasn't available anywhere when the NEX-5 came out..
I just looked into my library and had to admit that I hardly ever used it ... Well, here at least two shots I got at the beginning. I really like the lens. It's compact, well build and gives the pictures a unique look, so although it's not about sharpness, it does pretty well for most compositions and it's going to be good enough for most of the NEX-3/5-shooters out there. And hey, you were able to get it for 100 bucks with the double lens kit.
The 16mm is my main lens on the NEX-3. Wide open it isn't as sharp from corner to corner (and it doesn't render as "harsh") as other pancakes like the Panasonic 14mm or 20mm lenses on m4/3 cameras. However, the 16mm sharpens up very nicely when you stop down to f/4 or f/5.6.
This lens has really grown on me. When I first bought it I was disappointed because it wasn't as tack sharp wide open as my other pancake lenses, but the more I use it the more I realize it's a very convenient and fun lens.
Like I said some weeks ago, I haven't used it much past year. So I decided today to go out and shoot something with it. One reason was that I'm not plan to take the kit zoom with me as soon as I got the 50mm, but for the moments I need a wider lens, the 16mm could do the job, and it's small enough to fit in every pocket. Well, the results aren't as good as I hoped, but judge by yourself.

This is the only picture today I'm happy with. To be fair, the light conditions weren't good (I was a bit too late) and it was just a short trip. What you can see even in the resized version: The corner sharpness isn't good at all - stopped down at f/7.1!

Again stopped down to f/7.1. It isn't absolutely sharp even in the center, but center performance is okay for it's price. As far as I saw on many pictures, chromatic aberrations are well controlled.

Here's what you get wide open at f/2.8. Bokeh isn't good by any meaning, but it has character to me. Here's a 100%-crop of the image above:
I prefer 28mm equivalent to 24mm equivalent, but I'm finding the NEX 16 to be more versatile than I thought it would be. Just a couple snaps of my boys taken in a Korean grocery store with the NEX-C3 and 16/2.8:
