The Sigma 85mm f/1.4 EX DG HSM for Canon is a medium-telephoto standard lens for Canon EOS DSLRs. Key features include:

Canon EF mount: We carry this lens in multiple mounts with this one being the Canon version.

Fast-Aperture Portrait-Length. The Sigma 85mm f/1.4 is perfectly suited for portrait photography and low-light event photography.

Optics & Focusing. It uses Sigma’s aspherical and low-dispersion elements to provide optimum image quality. A Hyper Sonic Motor system gives fast and accurate autofocus performance on still and video cameras. Its circular nine-blade aperture ring allows for a smooth background blur, while the multi-layer lens coatings keeps pesky flares at bay.

Microfocus Woes. Please note this is an f/1.4 aperture lens. It’ll probably require autofocus microadjustment on your camera to give you sharp images wide open. If your camera does not have that feature, or you are not comfortable using it, please don’t rent this lens. If you’re not used to working with wide-aperture lenses, please read this link before deciding if this is a good choice for you.
