The Tokina 50-135mm f/2.8 AT-X 535 PRO DX Lens is a large-aperture telephoto zoom lens designed exclusively for use with digital SLR cameras. It features a fast constant aperture of f/2.8, and provides a focal length equivalent to 80-216mm in 35mm format. This zoom range covers a broad range of frequent telephoto situations. DX series lenses feature a smaller image circle (rear of lens) and are designed to match the smaller dimensions used for the image sensor on digital cameras. As a result these lenses are also more compact and lightweight, and are better matched to digital SLR cameras.

PopPhoto reviews the Tokina 50-135mm f/2.8 AT-X 535 PRO DX and writes;
“Our SQF tests found sharpness and contrast in the Excellent range at all focal lengths — an above-average performance, as many lenses in the category slip into the Very Good range at their long tele settings. DxO Analyzer 2.0 tests found Slight barrel distortion at 50mm (0.18%); Imperceptible pincushion distortion at 85mm (0.09%); and Slight pincushion distortion at 135mm (0.22%) — all excellent results. We found no light falloff at 50mm, and slight falloff at 85mm and 135mm, gone in both cases by f/3.5 — also exemplary. At the constant close-focus distance of about 39 inches, maximum magnification ratios ranged from 1:14.25 at 50mm to a respectable (but not great)1:5.42 at 135mm.”

Chester.sg has a comparison of Tokina 50-135mm f/2.8 AT-X 535 PRO DX to Sigma 50-150mm;
“In conclusion, both lenses perform comparatively at f8 but Sigma stands out at f2.8 (135mm). Again this test is not conclusive because of the limited test images obtained. Nevertheless, both lenses are a welcome offer to the digital SLR community, who has been limited with heavy f2.8 telephoto zooms at 70-200. Now with these 2 new lenses, photographers can have a more compact telephoto zoom lens.”
