Tamron Adaptall-2 135mm f/2.5 (03B) - Tamron Adaptall-2 Mount

The Tamron Adaptall-2 135mm f/2.5 (03B) is a compact, fast telephoto prime lens designed for 35mm SLR cameras. Its f/2.5 maximum aperture makes it a capable choice for portraiture and low-light photography, providing significant background separation. As part of the Adaptall-2 range, it features a removable mount system, ensuring compatibility with a wide array of vintage camera bodies. The lens is well-regarded for its robust all-metal barrel construction and smooth manual focus action. Potential buyers should examine the 03B for internal haze, particularly on the middle elements, which can affect contrast. SDS tests the manual focus ring for consistent resistance across the entire range, as dried grease can lead to stiff movement. The built-in retractable lens hood should slide smoothly and remain in place when extended. We also ensure the aperture diaphragm is clean and snaps shut correctly during testing.
