I've been needing a wide-angle lens for the longest time now and today it will arrive! I ordered the Sigma 18-50mm f/3.5-5.6 DC lens. Would love to have the f/2.8 version but I just don't have the money for that one. This one will have to do for now, but on the same token I've been using the slower and less expensive 28-80mm & 70-300mm Sigma lenses for over a year now and I've had good results from them so far, so I'm expecting about the same quality with this new lens. I'm really hoping tonight we'll get some clouds with the sunset so I can give this new lens a whirl!
