Sigma 85Mm F/1.4 Dg HSM Art Lens for Canon DSLR Camera

About this item

• This short telephoto 85mm f/1.4 prime lens is designed for full-frame format Canon EF-mount cameras and can also be used with APS-C models where it will provide a 136mm equivalent focal length
• Fast f/1.4 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques
• Two SLD elements and one element with a high rate of anomalous partial dispersion and a high index of refraction have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and help to ensure high image sharpness, clarity and contrast regardless of focus point or aperture setting - this optical design also helps to control distortion and limit vignetting
• A super multi-layer coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions
• The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance - the HSM also permits full-time manual focus control simply by rotating the focus ring at any time
