I am going to purchase a wide angle zoom for my Nikon F100. I am considering a Nikon 17-35/2.8 EDIF amd a Nikon 18-35/3.5-4.5 ED. The first is almost 3 times the cost as the second. However, the first IS a 2.8 lens. Is this faster lens in the wide angle worth the extra cost? Most of my work is with nature/landscape.
Thanks for the help.
