TOKINA 100mm f/2.8 for Canon

The Tokina 100mm f/2.8 macro lens offers a ratio of 1:1 at a focus distance of 30cm. The new multi-layered finish is adapted to the requirements of CCD or CMOS image sensors of today's digital SLR cameras. Its high-quality optics provide excellent sharpness across a 35mm film frame.
In addition, this lens features a focus range switch that allows you to define the focus range to suit your needs. The focus limit switch also increases the focusing speed in macro mode. The front flange does not rotate during focusing, allowing comfortable use of popular polarising filters or special effects such as a circular flash.
