135mm f/1.8 DG HSM "A" for EOS
Telephoto Prime Lens
Sophisticated optics come together with a sleek design in this Canon EF-mount 135mm f/1.8 DG HSM lens from Sigma. A prime telephoto lens designed for use with full-frame Canon EF-mount DSLRs, it can also be used on APS-C models where it will provide a 216mm equivalent focal length. As part of Sigma's Art series of lenses, it achieves truly outstanding performance.
Two F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements are featured in the optical design, and work to control colour fringing and chromatic aberrations for improved clarity and colour accuracy. A Super Multi-Layer Coating has also been applied to lens elements and enhances image quality by suppressing lens flare and ghosting. This is complimented by a bright f/1.8 maximum aperture and a rounded nine-blade diaphragm, allowing you to create images with selective focus and smooth out of focus areas, ideal for portraiture.
Alongside these imaging capabilities, the lens uses an integrated HSM (Hyper Sonic Motor) for quick, smooth, and quiet autofocus performance with full-time manual focus override. All this is housed inside a Thermally Stable Composite (TSC) lens body, a material that offers professional durability in a wide range of working environments. The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
This lens is also compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
