Compact apochromatic ultra-telephoto zoom
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.
It is incorporated with an aspherical lens and SLD (Special-Low-Dispersion)
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.
Rear focusing
The five-group zoom and rear focus systems ensure high performance stability and ease of use.
It is equipped with a detachable tripod
A removable tripod collar is included as a standard component.
