Sigma 105mm, f/2.8 EX DG OS HSM, Canon EF

The popular fast macro telephoto lens offers, in this new edition, numerous features that significantly enhance the handling of the lens, alongside its consistently outstanding performance. Thanks to Sigma's OS (Optical Stabilizer), handheld photography is extended by up to 4 stops, which helps to avoid camera shake at the small apertures commonly used in macro photography. An SLD (Special Low Dispersion) glass element and an SLD glass element with a high refractive index ensure excellent correction of all optical errors and distortion. The Floating Focusing System moves two different lens groups along the optical axis to different positions when focusing. This system effectively compensates for astigmatism and spherical aberration, delivering outstanding optical performance from infinity down to a 1:1 magnification. The length of the lens does not change during focusing thanks to this technology, simplifying the use of macro flash and allowing for the use of Sigma teleconverters, enabling a magnification of up to 2:1. The HSM (Hyper Sonic Motor) drive provides fast and almost silent autofocus, which can be manually overridden at any time. The use of nine diaphragm blades creates a nearly round aperture, resulting in a very pleasing bokeh outside the depth of field. The lens housing is splash-proof, making it well-equipped for use in harsher conditions.
