Kalt Auto Teleconverter 2x for Canon FD

The Kalt Auto Teleconverter 2x for Canon FD is a vintage optical accessory designed to double the effective focal length of any compatible Canon FD-mount manual-focus lens. By inserting between the camera body and the primary lens, it turns a standard 50mm prime into a 100mm telephoto, or a 135mm lens into a 270mm telephoto, offering added reach for sports, wildlife, and distant subjects without needing to carry extra lenses. It features full automatic diaphragm pass-through to maintain aperture coupling and exposure operation on classic Canon FD film SLR bodies and adapted mirrorless systems.
