Fast maximum aperture F2.8 telephoto lens optimized for digital SLR cameras.

The new multi layer lens coating reduces flare and ghost, which is a common problem with digital SLR cameras. ELD (Extraordinary Low Dispersion) glass elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast. It creates an excellent image quality with 35mm film SLR cameras as well as digital SLR cameras.
