Sigma 105mm f/2.8 EX Macro for Canon EF

The Sigma 105mm f/2.8 EX Macro is a third-party telephoto macro lens in Canon EF mount, offering true 1:1 magnification for close-up and macro photography alongside use as a short telephoto prime for portraits. The optical design incorporates SLD (Special Low Dispersion) glass elements to control chromatic aberration and maintain sharpness at close focusing distances. The EX-series build features a durable construction with a focus distance limiter switch to speed up autofocus acquisition by restricting the focus range. A floating internal focus system helps maintain image quality throughout the focusing range, from infinity down to the lens’s minimum focus distance. The lens is compatible with full-frame and APS-C Canon EF-mount bodies, and can be used on RF-mount cameras via Canon’s EF-EOS R adapter.
