The Sigma 85mm 1.4 DG HSM Art is the latest addition to the world renowned Sigma Global Vision line. Designed and engineered for unparalleled image quality, the Sigma 85mm 1.4 Art employs a completely new optical design and premium components. 2 FLD (performance equal to fluorite) glass elements and 1 element boasting a high rate of anomalous partial dispersion and high refraction achieve a class leading level of performance. The highly anticipated 85mm 1.4 Art is an ideal lens for a variety of photographic subjects, particularly portrait photography, both in-studio and on-location. The newly updated hyper sonic motor (HSM) allows for 1.3x the torque of previous generations for fast and efficient autofocus. Through rigorous testing, the Sigma 85mm 1.4 Art ushers in a new era of quality and performance for this popular fast prime focal length. A 9 blade rounded diaphragm creates beautiful background bokeh to isolate and accentuate the subject. Full time manual focus can be engaged by rotating the focusing ring, even when shooting continuous autofocus and a state-of-the-art electronic diaphragm is included for lenses in the Nikon mount.
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
