Tamron 28mm f/2.5 (02B) - Tamron Adaptall-2 Mount

The Tamron 28mm f/2.5 (model 02B) is a popular wide-angle prime lens within the Adaptall-2 system. It is significantly faster than the standard f/2.8 wide-angles of the time while remaining remarkably compact. This lens is known for providing sharp images with good contrast, especially when stopped down slightly. Its small size makes it an excellent choice for street photography on either film SLRs or modern digital bodies via adapters. Buyers should check for oil on the aperture blades, as this model can suffer from 'sticky' iris issues if stored in warm conditions. SDS ensures the focus helicoid is smooth and the infinity focus is accurate. The rear Adaptall fitting should be inspected for any bent pins or wear that might affect the mounting of adapters. We also check for internal dust or light haze that may affect contrast.
