Since 1975, Tamron introduced a new standard for mounting its lenses, which replaced the Adapt-A-Matic mount. Since 1979, a slightly improved design appeared as Adaptall-2. Both are fully compatible and have the same construction, but Adaptall-2 differs in improved Adaptall reliability (said the company Tamron).

Adaptall lenses were all launched in the 1972-78 timeframe, while Adaptall-2 lenses were all launched in the 1982-1996 timeframe. Ability of a lens to use Adaptall vs. Adaptall-2 mount is apparently not straightforward...one person noted, "Adaptall 2 lenses can indicate their maximum aperture to the mount, for fittings which require it. Not all cameras need this information, so some mounts are freely interchangeable between the two types of lens, and some aren't. Confusingly, some mounts are marked "Adaptall 2" when they're also compatible with Adaptall lenses..."

Difference between Adaptall and Adaptall 2

What is the difference between Tamron Adaptall and Adaptall 2 mounts. Are they interchangeable. Could a lens use Adaptall mount, also could use Adaptall 2, and vice versa.

The Adaptall lenses for Canon FD mount had a fixed pin to indicate maximum aperture to the camera body. I nearly came unstuck when I bought a Tamron 105mm f2.5 Adaptall lens which had an adaptor with a fixed f3.5 Adaptall mount. Took me a bit of running around to find the correct f2.5 Adaptall mount.

On the Adaptall-2 FD mount the max aperture pin is floating and is controlled by a fixed pin on the lens. Net result is that an Adaptall-2 FD mount can be used with any Adaptall-2 lens on an FD body.

Should also say that this lens was used on AE-1 and A-1 where shutter priority automation required full range of lens apertures to be available. I haven't used an FTb. If an FTb allows open aperture metering then it would also need the lens to indicate the max aperture correctly.
