The Vivitar 500mm F8.0 Telephoto Lens for T-mount is a super telephoto lens that makes distant objects seem closer, making it ideal for wildlife photography. It is also used for several common photography applications such as landscapes, cityscapes, architecture, sports, and astrophotography. The lens's multi-coating treatment achieves uniform light transmission and minimizes flare, allowing for sharp, high-contrast images. It has a built-in rotatable tripod collar, enabling vibration-free and stable shooting when used with a tripod or monopod. A T-mount adapter is required to attach this lens to a camera body, but it is compatible with almost all film or digital SLR cameras.
