This lens has a lot going for it and even though it isn't cheap the performance is very good for the price. It is in my opinion an excellent performer especially for the landscape photographer who is working with a DX sensor and I purchased it as a lens to satisfy the wide angle end of travel and...

Recommended... so far great quality

I don't know how I ever lived without an ultra-wide angle lens like this one. The lens is extremely well made. The manual focus to auto focus ring took a few to get used to, but it works great. Picture quality is fantastic. Lens flare is a definite problem with this camera though.

More than happy with this lens. I've gotten use to the push-pull auto/manual focus ring, and although I prefer a switch or the ability to simply manual focus in AF mode, this is not a deal breaker. I would absolutely buy this lens again.

Excellent lens, I can recommend it if you need a great wide angle, or just want to go under the standard 18mm.

I have only shot a couple hundred frames so far with this new lens, but can comment on observations. It seems to be a lens that produces sharp images, with good color. I noticed how little barrel distortion there is in the landscape photos I've taken. Horizons look surprisingly good.

Great wide angle lens.

Could only be better if it had VR, to increase low lighting situations.

great lens for a great price!!! Great quality and works great with my DX camera.

Low distortion and vingette. Some flare and CA but better than 11-16mm in my opinion. Color rendering a bit on the cool side. Warming filter or post adjustment may be appropriate. Pretty darn sharp with good contrast. Solid build quality. Prefer the manual focus ring to a little button.
