This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware. BulletPoint3 : For operation, a Hyper Sonic AF motor provides fast, accurate focusing and a large focusing ring permits manual focus override for making fine adjustments. A rounded 9-blade diaphragm also helps create round, smooth bokeh. It is made from a thermally-stable composite material that is light and durable and it has a brass bayonet mount. Additionally, it is fully compatible with Sigma's USB Dock. The bayonet mount is constructed from brass for ensured accuracy and durability. BulletPoint4 : As part of the Art line within Sigma's Global Vision series, this lens' is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications. 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. A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality. BulletPoint5 : Two SLD elements, one element with a high rate of anomalous partial dispersion and a high index of refraction, and one aspherical element 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.
