Tamron SP AF 90mm f/2.8 Macro

The Tamron SP AF 90mm f/2.8 Macro is a classic prime lens renowned for its 1:1 reproduction ratio and high optical clarity. It is a dual-purpose lens, serving as a dedicated macro tool for intricate detail and a sharp portrait lens with pleasing bokeh characteristics. The 'SP' (Super Performance) designation ensures high-quality glass coatings and construction suited for professional and enthusiast use on both full-frame and APS-C bodies. Potential buyers should inspect the 'clutch' mechanism used to switch between auto and manual focus, ensuring it clicks firmly into place. SDS examines the long internal barrel extension for smooth movement and checks that there is no excessive play in the mount. As an older design, the external focus movement should be checked for consistency and the glass inspected for any internal dust.
