Combining reach and speed, the Canon EF-mountSigma APO 300mm f/2.8 EX DG HSMis a super-telephoto prime also characterized by its advanced optical and physical design. Its fast f/2.8 maximum aperture aids in isolating subjects using depth of field and also supports working in low-light conditions. Designated an apochromat, this lens uses a pair of extra-low dispersion elements to effectively eliminate color fringing and chromatic aberrations for high clarity and color accuracy throughout the aperture range. A multi-layer coating has also been applied to lens elements to control flare and ghosting for improved contrast and clarity.

Benefitting the optical attributes is a Hyper Sonic Motor, which provides quick, smooth, and quiet autofocus performance with full-time manual focus override. The physical design also incorporates a removable, rotating tripod collar for easy attachment to a tripod or monopod, and a drop-in filter slot permits working with rear 46mm filters, such as the included circular polarizer filter.

Super telephoto prime is designed for full-frame Canon EF-mount cameras, however can also be used with APS-C models where it provides a 480mm equivalent focal length.
Impressively bright f/2.8 maximum aperture suits working in available light conditions and also affords increased control over depth of field.
Apochromatic optical design utilizes two extra-low dispersion elements to significantly reduce color fringing and chromatic aberrations for increased clarity and color fidelity.
Multi-layer coating has been applied to individual elements to minimize flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions.
Hyper Sonic Motor (HSM) realizes quick and quiet autofocus performance as well as full-time manual focus override.
Internal focusing design maintains the overall length of the lens during use and also promotes faster performance.
Nine-blade diaphragm contributes to a pleasing bokeh quality.
A removable, rotating tripod collar offers well-balanced support for photographing atop a tripod or monopod with either vertical or horizontal shooting orientations.
Rear drop-in 46mm filters can be used and a circular polarizer filter is included for reducing reflections and increasing contrast and saturation.
