The T2 lens mount, also known as T-mount or T-thread, is a standard for connecting camera lenses to cameras or other optical devices. It was developed by Tamron but has since been adopted as a universal mount for a wide range of cameras and optical equipment. With the use of an adapter, you could mount it onto various analog cameras.
