Excerpt: 18-36mm lenses have long been many photographers' standard short zooms for full-frame shooting. Here's the equivalent of that range in a 1.5X 35mm lens factor for small-format digital Nikon SLRs only. Small DX image circle allows compact size with constant aperture.
Conclusion: Nikon were the first to produce a dedicated ultra wide angle lens for their cropped sensor cameras and they obviously put all their experience of both SLR lenses and wide angle for smaller sensor (Coolpix) lenses to full use.
Pros: Superb optical quality, Compact and well built, Silent autofocus
Cons: Price, Slight pincushion throughout (Being picky!)
Excerpt: Nikon's 12-24mm has a constant maximum aperture of f/4 through the entire zoom range, stopping down to f/22. On a Nikon D-SLR with a 1.5x focal length multiplication, it has a 35mm equivalent of 18-36mm, offering plenty of wide-angle coverage.
Excerpt: Build and Handling This lens is smaller than you would expect, especially if you have used fastish wide-angle lenses on a 35mm film body. In fact, it is not a lot bigger than the 18-70mm kit lens that Nikon make in the same DX format.
Pros: In summary the main positive points of the Nikon AF-S 12-24mm f/4 DX G ED are:, Superb optical quality, Compact and well built, Silent autofocus
Cons: Negative points are:, Price, Slight pincushion throughout (Being picky!)
