For sale is a vintage Auto Teleconverter 3X for Minolta SR / MC / MD mount, made in Japan.
This is a manual-era teleconverter designed to fit between a Minolta manual-focus film camera body and a compatible Minolta SR / MC / MD mount lens. It multiplies the focal length of the attached lens by 3x, turning a 50mm lens into roughly 150mm, a 135mm lens into roughly 405mm, and a 200mm lens into roughly 600mm.
Like most 3x teleconverters, it also reduces effective light transmission. A 3x converter costs roughly 3 stops of light, so an f/2 lens behaves closer to f/5.6, an f/2.8 lens behaves closer to f/8, and an f/4 lens behaves closer to f/11. Best results are generally with sharper prime lenses and brighter telephoto lenses.
This is a vintage accessory from the manual-focus film era, with metal construction, aperture coupling, and a mechanical feel typical of Japanese third-party camera accessories from the 1970s and 1980s. It’s useful for Minolta film shooters, collectors, or anyone putting together a vintage Minolta kit and wanting extra reach without buying a much longer lens.
It uses the Minolta SR mount, commonly referred to as MC / MD mount, and is intended for Minolta manual-focus film bodies such as the SRT series, XE series, XD series, XG series, and X-700. It can also be adapted to modern mirrorless systems if used with Minolta SR / MC / MD lenses and the correct adapter.
This is not a modern high-performance teleconverter. It’s a characterful, practical vintage accessory that adds reach, with the usual trade-offs in light loss, contrast, sharpness, and handling. Tiny reach-stretching goblin. Useful, but physics still sends the invoice.
