Hi Noobiba and samsungfreak,
I'm not sure if this can be used to convince you guys otherwise regarding your sentiments on the 16.. f/2.8 lens, but I don't seem to have any issues with it even with a very basic NEX3. Furthermore, as you know attaching anything to the front of any lens will definitely degrade the image quality by a fair bit however little it may be.
But do consider looking through these images in my blog and give your opinion on my so-so images... taken with NEX3 with 16mm f/2.8 lens with fisheye adapter in front.

Nice shot bro. The 16 is sharp at the center but very bad at the corner. The photo you show does not have corner details on right but some on the left. See how the bridge details fall off dramatically near the border. If you shoot wide open or use it with the 23mp Nex 7, it will be even worst.
This lens has no corner resolution according to Photozone.

I have not seen anything as bad.
http://slrgear.com/reviews/showproduct.php/product/1346 state the same with blur index up to 7 units, something you don't see with other lenses.
The kit lens do a lot better. But still almost all Nex lenses are not very good at corner due to larger APS-C sensor, but the 16mm is simply the worst.

So basically, what you're saying is that you've only read about it and have not tested it personally? 16mm vignettes badly? Sorry, I don't see it. Just taken out my 16mm and tested at all apertures. Doesn't seem to affect much even when shooting on a white wall. Stopped down, yes, it does sharpen the image up.
16mm indeed vignettes badly. Photozone state it to 3EV, making it #1 in all lenses! It is the reason why the corner is not sharp because the corner don't receive much light and require vignetting correction and perceptive correction that blur it even more. I am sure you have turn on "vignetting correction" in your camera where the camera will brightened the corner for you post captured. I heard online that this setting will affect the RAW file but I cannot confirm it.
