Legacy Lenses 2 - Tamron SP 90mm F2.5 Macro (Adaptall)

The second lens in this series is the superb but somewhat underrated Tamron SP 90mm F2.5 Macro. It's a beautifully made lens, tack sharp and relatively compact for a 90mm macro. It's an 8-element, 6-group design.

Besides its optical quality, the mounting system worth mentioning. It's the now-defunct Tamron Adaptall mount. It can be changed by the user in 30 seconds. I have mounts for M42 screw mount, Rollei QBM, Pentax KA, Canon FD, Nikon F and Olympus OM.

Tamron SP 90mm F2.5 Macro (model 52BB)
Manual Focus - Adaptall-2 mount

There are two models, the early 52B and the late 52BB . The 52B has a close-up accessory lens that allows making 1:1 macro. The 52BB is a 1:2 macro.

Not a Leica APO Macro Elmarit 100mm, but not too far. It's on par with the Canon EF 100mm Macro on optical quality for a fraction of the cost. It's a perfect general purpose mid-telephoto lens.

It's a bargain and worth every cent !
