Thanks for the info.I would appreciate a sample if possble.I am pretty much an aperture priorty guy anyway.Spent most of my life with a 6 x 6 Bronica and a light meter before going digital.
I will check out the lens you mentioned.I have a sigma 10 - 20 which I have found great for wide angle shots.I now use a Nikon D100  and I have a Nikon 70 - 300mm zoom and a Nikon 24 - 85 but the price of Nikon lens's is frightening compared to Sigma.
Thanks again.
Eddie
