BlattWorld, Item Details: Tokina 24-200/3.5-5.6 ATX

The AT-X 242 AF is the first lens to start at 24mm and zoom all the way to 200mm, and is currently the widest zoom range available starting at 24mm. It is constructed using a chrome plated brass mount plate and a combination of aluminum and composite lens

barrels to reduce weight while maintaining strength and durability. Optically, the 242 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 employed 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.
