Tokina 100mm f/2.8 AT-X M100 AF Pro D Macro Autofocus Lens for Canon EOS is a macro lens capable of life-sized (1:1) reproduction at 11.8" (30 cm).
The lens' multi-coating has been re-engineered to match the highly reflective silicon based CCD and CMOS sensors in today's digital SLR cameras. This lens gives the best of both worlds because optics still give full coverage and excellent sharpness on 35mm film. A macro lens that can handle both the digital and film worlds with ease.
Focus Limit Switch
Focus limit switch that can lock the focus out of the closest focus making it focus faster when used as a moderate telephoto lens and is excellent for portraits as well
