comment:It's one of my favorite lenses, and find itself on my camera often. It's ridiculous how wide it is if it's your first extreme UWA lens, and is a lot of fun to use.

It's distortion characteristics are easy enough to correct in PP, and performs well even from f/3.5 throughout the zoom range. Has a definite learning curve due to its nature, but for landscapes, architecture, and even portraits, makes you look at everything differently. I love it, and wouldn't hesitate recommending it due to this version having the HSM for Sony, but otherwise, the Sigma 10-20/4-5.6 variant is better in its regard to distortion and even sharpness [a win if you shoot with CaNikon with HSM].
