Summary: I used this lens with the panasonic AF100 so my review may not be relevant for DSLR users, but I hated this lens. Everything about it really, the construction is really crappy plastic, the image is bad and if you plan on manually focusing this lens think again! beware!
Summary: Like many others I was debating between this and the 20-35 and 17-35..but it all comes down to what your needs are and how deep your pockets are..right? I wanted a lens for landscape and this fit the bill nicely. If you plan on using a tripod, you don't need fast glass anyhow..right? This lens does struggle in low-light, hand held..but like I said..what are your needs? If you are in need of a landscape wide angle lens and want to save some bucks..this is it.
For the price, you can't find a better alternative than this.

Summary: Skip any aftermarket lens in similar zoom range and get this, sharp and contrasty, zoom is fairly good best for use with full frame cameras traveling on the light, uses your standard 77mm filter (probably need a slim filter.
Summary: This replaced an unfortunate Tamron WA purchase which I regretted immediately. For the price I don't think you can get better Nikon optics. Distortion is fairly high at the widest end and you get vignetting at 18mm if using with a standard thickness filter. Construction feels solid. Recently there appears to be a dust spot that's worked its way into the lens but after backpacking around the world for a year I guess that's to be expected.
Summary: This is less a review than a correction to Amazon's description of the product pending the update I requested. This lens does not as stated come with an 72mm lens cap. It comes with a 77mm lens cap, and uses 77mm filters. I had to return the filters I bought with this lens, since they were the wrong size. Check out the Nikon USA and Adorama web sites for confirmation on this.
