Tamron 35-135mm f/3.5-4.5 — Adaptall-2 CF Macro travel zoom (40A), multi-mount fit
Tamron's 35-135mm f/3.5-4.5 arrived in 1985 as model 40A within the Adaptall-2 system, replacing the earlier 22A of the same focal range with an updated design. It stayed in the catalogue into the mid-1990s, spanning the shift from manual-focus SLRs to the early autofocus era.
As a CF Macro zoom, the 40A combines a general-purpose 35-135mm range with close focus to roughly 1:4 magnification at the long end, a feature Tamron marketed on its 1980s consumer zooms. It mounts via interchangeable Adaptall-2 adapters: Canon FD, Nikon F, Minolta MD, Olympus OM, Pentax K, Konica AR, Contax/Yashica and M42.
The nearly 4x range made it a practical single-lens travel option before affordable superzooms became common, covering wide-angle through short telephoto without a lens change. Sharpness is typical of mid-1980s consumer zoom design, softer wide open at the long end than the primes it replaced.
These zooms are inexpensive and widely available with a range of Adaptall adapters. Worth checking zoom and focus rings for grease migration onto the aperture blades, verifying the macro switch engages smoothly, and confirming the adapter fits the intended camera before buying.
