I have an engagment session and a wedding to shoot and am short on lenses and equipment. I use a D70 at the moment, but I am desperate need of a good all round lense that I can use outdoors and indoors and all the rigors that wedding photography will throw at me. I have narrowed it down to three lenses to chose from: Nikon 28-70mm f/2.8D ED-IF AF-S Zoom Nikkor Lens Nikon 17-35mm f/2.8D ED-IF AF-S Zoom Nikkor Lens Nikon 70-200mm f/2.8G ED-IF AF-S VR Zoom Nikkor Lens Which do you recommend, and if none of the three above, which one can you suggest that will be a great all rounder for me. They are expensive and I can unfortunately only afford just the one at this time.... I just cant decide and also do not have the experience to make a good decision here on my own - help please!
