I would like to buy a wide angle zoom lens. The Nikon 12-24 is certainly an option, but the Sigma 10-20 also seems to have its share of fans. I would appreciate the comments of anyone who has used both. I know the Sigma is a variable aperture while the 12-24 is fixed at f/4, but I am more interesed in sharpness, IQ, CA, distortion, etc. Please offer any comments you think would help with this decision. Of course the price of the Sigma is also more attractive than the Nikon, but price isn't everything.
Thanks in advance for your help.
