I've seen reviews of this lens veering from excellent to mediocre. I'd liked to have given it a three and a half star rating.
Starting out in ultrawideangle zooms with a Sirius 18-28mm, many, many years ago, I really enjoyed the freedom the extra width gave me, especially around cityscapes.
This Nikon was its replacement. I used it on a Nikon F80 and F100. I now use a full-frame Nikon D700. I found out quickly that to get a good, contrasty (punchy is an oft used word), especially at the wide end, barrel distortion is the downside. Straight walls at the edges and the sea at the top of the pictures get bowed out. Though better than the Sirius in this respect, it gets more annoying as you progress with your hobby.
Landscapes, though, really did render well, with a lovely sweep of perspective, natural colour and with biting detail. Unlike more pretentious (and costly) lenses, the relatively moderate filter size allows the wonderful world of polariser and graduated grey filters. An interesting sky can be transformed by their use.
The lens is also a handy size. And decently robust, inspiring confidence.
I (very much) part exchanged the 18-35 for my dream lens in this field - a Nikon's 17-35mm f2.8, (secondhand) which I also review. A pro lens that costs up to three times the cost of this one. However, I'd have to question whether the 18-35 reviewed here offers the best value option these days. Independent lenses have made leaps and bounds and therefore might be a better buy. Especially for DX DSLR users, as the ultra-wideangle 18mm on a FX one is merely around 28mm on a DX and then it's only 2x zoom ratio.
There's no doubt that I had a better trade in deal because it had 'Nikon' stamped on the barrel, though.
