This vintage Tamron Converto lens is a great addition to any photographer's collection. With a maximum aperture of f/2.8, it is perfect for capturing stunning portraits and detailed shots. The lens is compatible with both Canon FD and Sony E mount cameras through the use of a T-mount to FD and FD to Sony E NEX adapter, making it a versatile option for any photographer. The lens has a manual focus type and an exterior made of durable aluminum. Overall, this Tamron Converto lens is a reliable choice for capturing high-quality photographs.  This is preset lens with 12 blades, great for video work.  Optics are in good condition, minor dust/lint, and minor cleaning marks, working aperture and smooth focusing.  The lens is a native T-mount, but I am including the T- to FD to and the FD to Sony E.   The original 225 converter is also included.  Test shots taken with a Sony a7Rii.  The Albinar bonus lens has been modified to produce a highly distorted swirly background.   The Tamron hood is also included.  Please note that the FD mount has been set to lock (previous owner), it works fine, but the open-lock ring will not move, also the adapter was very tight on my a7Rii, but worked fine on my a7S.
