Read the interesting review about one of the more unique wide angle lenses. The review is quite thorough and luckily the lens is equally good.

The Sigma AF 8-16mm f/4.5-5.6 DC HSM may be the new star in this lens segment. It’s very sharp across the whole range straight from the max. aperture. Lateral CAs are also very well controlled. That’s quite an achievement for such an extreme ultra-wide angle zoom lens!”
