Tokina AT-X 100 PRO D lens for digital and film SLR cameras.
The AT-X M100 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, while the optics still give full coverage and excellent sharpness on 35mm film.
The AT-X M100 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 or portrait lens.
Other features of the AT-X M100 PRO D are:
Tokina One Touch Focus Clutch Mechanism for fast easy switching between manual and Auto focus.
55mm non-rotating filter thread for use with macro ring flashes and special effects filters.
