The Tokina AT-X M100 AF 100mm f/2.8 is a new macro lens for digital and film SLR cameras. Keeping up with current technologies, this lens features re-engineered multi-coating to match the highly reflective silicon based CCD and CMOS sensors in today’s DSLR cameras. The AT-X M100 PRO D also has a handy focus limiter switch, making it focus quicker when used as a moderate telephoto or for portraits.
