Sigma 70-300mm f/4-5.6 DG APO Macro Motorized Telephoto Zoom Lens for Nikon SLR Cameras - SOLD
"...The best lens in this price range.." - DP Review
"...From an optical standpoint, the lens is incredibly good, considering the price. I fired off about 70 shots outside to test the aperture at the different focal ranges. Yes, there is some softness at 300mm, but this can be mostly offset by stopping it down to 4.0. The rest of the focal range is fine. I used my Nikon D90 and a UV filter (50mm) for the tests. In the macro mode, there's excellent contrast and saturation, and very good bokeh. ..." - buyer # 4
