The Kiwi Lens Mount Adapter - T-Sony A allows you to mount a T Mount lens onto a Sony Alpha camera body. The all-metal adapter is designed to fit the lens securely, yet can still be removed easily when not needed. Allows the use of T mount lens (Telescopes, microscopes, enlargers, bellows units etc.) to Sony Alpha DSLR/(Konica) Minolta AF/Alpha/Dynax/Maxxum camera. Since there is no data transfer between the camera and the lens, focusing and aperture must be set manually. Preserve all focusing range up to the infinity point.
