Description — Sigma 50mm f/2.8 Macro
The Sigma AF 50mm f/2.8 EX DG Macro is a prime lens built for full-frame DSLR cameras, available across five mount systems: Canon EF, Nikon F, Sony A, Pentax K, and Sigma SA. With a fixed 50mm focal length and a maximum aperture of f/2.8, it sits in the standard focal length range and is categorized as a macro-type lens within Sigma's EX DG product line. The lens supports both autofocus and manual focus, offering flexibility for different shooting scenarios — whether that's standard shooting with AF engaged or precise manual control for close-up work.
It accepts 55mm front filters, a common size that keeps filter costs accessible. At 320g, the lens is compact and easy to carry, though it carries no image stabilization, so steady technique or physical support is recommended when shooting in challenging conditions. This lens is aimed squarely at DSLR shooters who want a dedicated macro-capable prime with wide mount compatibility and full-frame coverage.
