BlattWorld, Item Details: Tokina 24-200mm f/3.5-5.6 AT-X 242 AF

The AF24-200mm f/3.5-5.6 AT-X uses high quality optical glass multicoated lens elements created by Hoya Corporation, the world’s largest manufacturer of optical glass. Two Aspherical lens elements and one SD (super low dispersion) glass element are employ

ed in the optical design to insure sharpness across the film plane. The aspherical elements are each molded as one piece of optical glass rather than a resin laminated to a glass core. An internal focusing mechanism gives this lens fast auto focus. Inte

rnal focus means the 72mm filter threads do not move during focusing. This is of great advantage when a special effects filter, such as a circular polarizer, is used. With an internal focusing lens it is not necessary to readjust the position of the filte

r every time the focus is changed. Focus distance is indicated on the manual focus ring.
