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.
The new multi layer lens coating reduces flare and ghost, which is a common problem with digital SLR cameras. ELD (Extraordinary Low Dispersion) glass elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast. It creates an excellent image quality with 35mm film SLR cameras as well as digital SLR cameras. Compatible digital camera chart This new lens has a special coating to reduce internal reflection and minimize flare and ghost, which is a common problem with digital cameras and also creates an optimum color balance. This lens uses two ELD glass elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast. It also features a drop-in 46mm filter holder in the rear part of the lens barrel, which can be rotated to facilitate the use of filters, including a polarizing filter. The HSM models (Sigma, Nikon and Canon mounts) provide fast, silent AF function as well as full- time manual focus override. It also incorporates inner focusing system, which enables responsive and fast auto focus speed. The overall length of the lens does not change during focusing, ensuring convenient handling and ease of use. Simply adding an APO teleconverter (optional extra), means that this lens can be used as a 420mm F4 AF ultra-telephoto lens with a 1.4X EX teleconverter, or a 600mm F5.6 AF ultra-telephoto lens with a 2X teleconverter.OTHERSAPO 300mm F2.8 EX DG HSM
