If you have a collection of 35mm SLR cameras from the 1970's and 80s with a variety of different mounts then buying a complete set of lenses for each lens mount rapidly becomes an expensive process even if each individual lens doesn't cost very much.
But there is an answer to this problem... Tamron Adaptall lenses.
Today Tamron make fixed mount lenses much like everyone else's lenses... but back in the 1970s and 80s they made a range of lenses with interchangeable mounts. And these mounts weren't like the dumb mounts you might be using to mound old lenses on your compact system camera.
These mounts integrate completely with the lens to create something that operates just like a fixed mount lens.
Tamron made 3 main ranges of interchangeable mounts:
1969-1973: Adapt-A-Matic
1973-1979: Adaptall
1979-2006: Adaptall 2
These mounts, particularly the amazing Adaptall 2 mounts made from 1979 onwards, were masterpieces of engineering that no other manufacture was ever able to compete with. Put the correct Adaptall 2 mount on your lenses and all the automatic exposure modes (including fully automatic and shutter speed priority modes) and metering facilities of your camera worked just as if you were using a fixed mount lens.
But as camera technology advanced and more and more communication between lens and camera was needed even Tamron's genius engineers met their limits. In particular autofocus SLR cameras defeated their engineering ingenuity, and Tamron never managed to create an interchangeable mount system for these cameras.
I've been meaning to build a small collection of Tamron Adaptall 2 lenses for my collection of 1970s and 80s SLRs for a while, and recently I've been making good on this ambition. Here you can see 5 Tamron lenses along with a Pentax Super A, and with the correct Pentax K-A mount all the Super A's many automatic modes work very nicely. The lenses in the picture are from left to right behind the camera:
Tamron Adaptall 2 24mm f/2.5
Tamron Adaptall 2 SP 90mm f/2.5 Macro
Tamron Adaptall 2 80-210mm f/3.8-4
Tamron Adaptall 2 70-150mm f/3.5
And mounted on the camera:
Tamron Adaptall 2 SP 28-80mm f/3.5-4.2
