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.

Optimized for use with digital cameras

Focus limit switch that can lock the focus out of the closest focus making it focus faster when used as a moderate telephoto lens that is excellent for portraits as well

One Touch Focus Clutch Mechanism for fast and easy switching between manual and Auto focus from any position

55mm non-rotating filter thread for use with macro ring flashes and special effects filters
