And i produce some great images out of this lens whether it was night or day.

Produces awesome image on my Sony a6000.

Lens caps are not very secure and the carrying case is quite bulky, but lens captures fantastic images!

It is clearly far better in every way, except that last little bit of wideness, than the Sony 16 and I do not think using even exotic and vastly more expensive lenses will result in a noticeably superior image (although I would use them if I had them!).On a Nex this is a 28mm lens, not terribly wide but very useful for those of use who do not get into the extreme wide angles

Thanks Sigma for providing a direct lens solution that focuses very fast, and makes excellent images

Other than that it is very sharp and gives a great image.

Sharp images, very good picture quality, not good for Macro shots

Great Price, good build quality, pretty fast focus, very clean image quality.

Overall, fantastic image quality and worth even more than the price paid!

The image is sharp

The reason for all of this effort is that this lens makes beautiful images

It output sharp looking images and looks really good in mono b/w.

I thought a lot about keeping this lens just because the images are so damn sharp

Will work in a pinch but don't expect a sharp image.

Sharp images and no problem at all with auto focusing

The images are very sharp and rich with detail

Some of my best images from this weekend came at at aperture of 5 and above

If you keep it in auto focus for video you will get this nasty jittery image, completely unusable

I do own some Contax G lenses which I love but the 28 has some issues on edges as does my 21 F4
