Combining reach and speed, the Nikon F-mount Sigma APO 300mm f/2.8 EX DG HSM is 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.
