The AT-X 100 PRO D is a new macro lens capable of life-sized (1:1)
reproduction at 11.8 in. (30 cm). The lens' multi-coating have 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.
The AT-X 100 PRO D also has a very convenient focus limiter switch that can lock
the focus out of the closes focus making it focus faster when used as a moderate
telephoto lens that is excellent portraits as well.
