Tamron's vintage close-focus 135mm — Adaptall mount system with f/2.5 and close-focus capability.
The Tamron 135mm f/2.5 Close Focus Adaptall is a medium-telephoto prime from Tamron's Adaptall system, featuring enhanced close-focus capability versus standard 135mm designs. The Adaptall system uses interchangeable mount adapters, allowing the same lens body to be fitted with adapters for different camera mounts. Manual focus only.
f/2.5 maximum aperture. 135mm focal length. Close Focus designation (enhanced minimum focus distance). Tamron Adaptall interchangeable mount system — no fixed mount (requires Adaptall adapter for specific camera body). Manual focus only. At approximately 370g.
The Tamron Adaptall (and later Adaptall-2) system allowed a single lens to be used across different camera brands by swapping a small mount adapter ring at the rear of the lens — Nikon F, Canon FD, Minolta MD, Pentax K, and others were all supported. The Close Focus designation indicates a shorter minimum focus distance than a standard 135mm, useful for portrait and detail work.
On the used market the Tamron 135mm f/2.5 Close Focus Adaptall is available as a vintage adaptable telephoto. Condition checks: Adaptall adapter included and compatible with target camera system, front element for haze or fungus, aperture blade smoothness, focus ring action. Confirm the Adaptall or Adaptall-2 variant and which mount adapter is included.
