This is a monster of a zoom lens. I really liked the colors it gave, the contrast and sharpness. But it was only sharp from 85mm to 250mm. Somewhat soft at 50 and 300mm but still gave usable images. Really needs to be used on a tripod unless you hoot at speeds above 1/2000. Did not like the screw on front cap and used an extra 400mm F4.5 front bag cap instead.
