This Ultimaxx 500mm f/8.0 preset telephoto lens is a manual, high-power option for SLR/DSLR cameras using a T-mount adapter and includes the 2x converter to extend reach to 1000mm. The lens barrel is precision-built from lightweight aluminum alloy for durability without excess weight. Its multi-coated, anti-reflection high index/low dispersion optical design minimizes flare and produces crisp, detailed, high-contrast images even in challenging lighting conditions. Aperture is preset from f/8.0 to f/32, preserving a wide range of exposure and depth-of-field control. Engineered to support both day and night shooting, it offers maximum light and image transmission while keeping distortion to a minimum. Kit extras include a rotating tripod mount, front and rear lens caps, and a soft carrying case for transport and protection.
