It Seemed Like a Good Idea at the Time

The Tamron Adaptall 2 system has been discontinued. Tamron pulled the plug on further development of the interchangeable lens mount concept several years back. Never an overwhelming success in the marketplace, in recent years this product line has served primarily as a means for owners of cameras with orphaned lens mounts and poor support from independent vendors (e.g. Mamiya ZE, Fujica AX, Praktica B200) to get at least some new glass for their cameras.

As long as lens mounts were mechanical and the lenses were worth having, it was a good idea, since it generally preserved features like auto-aperture function with all mounts. Unfortunately, AF SLR lens mounts are electronic, and though there were a few outstanding Tamron SP lenses--the SP 90mm/2.5 macro that outperformed the comparable Leitz lens of its day according to reports published at the time, the SP 35-105/2.8 ASP constant aperture zoom, and the SP 300/2.8--the same could not be said of all the lenses in the system.

Now if those new Zeiss lenses could come in maybe a slightly more rugged version of the Adaptall II mount, that might be something interesting.

David -

I wonder whether the breaking point wasn't just the introduction of AF, in particular AF driven mechanically from the body. Even before that, it was hard enough translating the wide array of ever more complex mechanical linkages for aperture control while maintaining reliable operation.
