It is an Apochromatic ultra-telephoto lens with a fast F5.6 maximum aperture, and incorporates two Extraordinary Low Dispersion glass elements (Abbe number 90.3), to reduce chromatic aberration to minimum limit.

This new lens also incorporates a rotary filter holder in the rear part of the lens barrel, which enables the use of a polarizing filter.
