Tamron 17-35mm f/2.8 Di Lens Review at Photo.net
Photo.net have just reviewed the Tamron 17-35mm f/2.8-4 Di Lens. The 17-35mm lens has a fast aperture of f/2.8 at its widest angle. The lens gives an angle of view equivalent to 28-55mm on a digital SLR camera (as most digital SLRs have APS-C sized CCDs).
“The Tamron SP AF17-35/2.8-4 Di LD Aspherical (IF) is a well built lens with overall good performance. At 17mm it’s very good and can be used wide open at f2.8 without much worry about image quality. The only negative is noticeable barrel distortion which could be a problem in some circumstances. Chromatic aberration is present but fairly well controlled throughout the zoom range. At 35mm the lens is slower (f4) and a little less sharp, though distortion is low.”
