Product Description
This compact apochromatic ultra-telephoto zoom lens covers frequently used 400 mm focal length. It is the ideal lens for shooting sports, nature, wildlife, landscapes and other types of photography that frequently use this telephoto range.This lens uses one aspherical lens and three SLD (the special low dispersion) glasses for excellent correction of chromatic aberration. Color aberration in the secondary spectrum is compensated by using three pieces of Special Low-Dispersion glass (SLD), and making high-quality images a reality throughout the entire zoom range.The five-group zoom and rear focus systems ensure high performance stability and ease of use.A removable tripod collar is included as a standard component.
