Contax T2 Mount Adapter

"Contax T2 Mount Adapter" replace camera lens. Any T2 mount thread attachment or lens can be screwed on directly in place of camera lens.




The "T" is said to stand for Tamron, a Japanese manufacturer, who in 1957 made a line of aftermarket camera lenses all using their T2 T-mount as a universal fit to 35mm SLR cameras of various manufacturers.The original T Mount slides onto a T mount lens. It is secured only by 3 set screws that match a channel on the lens mount so that the lens barrel is not deformed by the set screws, and it can therefore be removed with no problem.

 

Besides cameras, applications include optical breadboard prototyping components, and telescope and microscope attachments. As a common mechanical interface, T-mount allows components of various manufacturers to be interchanged and assembled.

 

Other large format camera lenses have flange distance longer than 55mm. They can be attached to smaller format cameras with a combination of corresponding lens-to- T-mount-adapter and a T2-Ring.

 

The T-mount is the standard way to mount a camera to a microscope to photograph pathological specimen slides.


T-mount has a long flange distance of 55mm and most 35mm cameras have shorter flange distances, a simple mechanical adapter called T/T2-Ring is needed to adapt a T-mount lens to any camera body without optical correction to achieve infinity focus.The differences between T-Ring and T2-Ring is that a T2-Ring consists of an inner ring with T-mount thread and an external ring with corresponding lens mount. Both rings are held together by 3 peripheral screws on the external ring. Slackening these screws allows rotation between the lens and the camera body. This is especially useful when the camera body is attached to telescopes or microscopes.

Non-Auto camera lenses, slide-duplicators, bellow units, astronomical telescopes, microscope adapters and a number of other attachments can be mounted onto various SLR camera bodies with the help of relevant T-2 adapters.

Standard T2-Rings have the same external diameter of the inner ring. The reason is that some T-mount lenses have their inner ring built on the flange.Other large format camera lenses have flange distance longer than 55mm. They can be attached to smaller format cameras with a combination of corresponding lens-to- T-mount-adapter and a T2-Ring.
