500mm f/8 Telephoto Lens (T Mount) with 2x Teleconverter (=1000mm) for Canon T4i, T5, T5i

This powerful 500mm f/8 Manual Focus Telephoto Lens utilizes aluminum alloy construction, computer-designed all-glass optics and the latest optical multi-coating techniques to provide crisp, high-contrast, virtually flare-free images of distant subjects, even under adverse lighting conditions. It features an aperture range of f/8 - f/32 and a rotating tripod mount, and it comes with a soft carrying case. Perfect for nature, sports and surveillance photography.
This 2x teleconverter attaches to any T-mount (screw mount) lens, and effectively doubles the focal length of that lens, allowing the photographer to get much closer to the action. This simple, yet high-grade adapter provides excellent optical quality at an affordable price.
