Photokina – Sigma has added the 85 mm f/1.4 DG HSM Art, 12-24 mm f/4 DG HSM Art and 500 mm f/4 DG OS HSM Sport to its Global Vision lens line.
The 85 mm lens is engineered to support the highest resolution sensors on the market with an exceptional degree of sharpness. The high-performance optical system is purpose-built by Sigma to produce an attractive bokeh effect. The lens’ advanced architecture features two SLD (special low dispersion) glass elements and one glass element with a high rate of anomalous partial dispersion and refraction. A re-engineered AF system brings 1.3X the torque of its predecessor, while other features such as a full-time manual focus override have been added, which can be controlled when the focus ring is rotated, even during continuous AF.
The Sigma 85 mm f/1.4 DG HSM Art lens supports Canon, Nikon and Sigma mounts. The Nikon mounts feature a brand new electromagnetic diaphragm. The lens will be available in late October.
The 12-24 mm lens features the largest aspherical glass mold in the industry, offering photographers an ultra-wide angle zoom with virtually no distortion, flare or ghosting. Lens performance highlights include constant f/4 brightness and the brand new Sigma AF system with 1.3X torque boost. The lens features elements made with FLD (“F” Low Dispersion) glass, which is equivalent to calcium fluorite in performance. Combined with an optimized power distribution, the result is outstanding image quality from center to edges. Minimum focus distance is 9.4 inches at 24 mm.

The flagship Sigma super telephoto 500 mm lens incorporates the very latest in Sigma optical technology and innovation. Designed for the professional sports and wildlife shooter, the ultra-durable lens features magnesium alloy components, a carbon fibre hood, a water and oil resistant front element, and is dust and splash proof. The lens features a drop-in rear filter slot for polarizers, UV and other filters.
The lens incorporates two FLD and one SLD glass elements, while the optimized power distribution helps minimize spherical aberration and axial chromatic aberration. The optical system also effectively minimizes transverse chromatic aberration, which can affect the edges of the shots taken in the telephoto range. In addition, image quality remains exceptional when the lens is used with a Sigma Telephoto Converter (sold separately).
Other key performance features include Sigma’s two-mode Optical Stabilizer for enhanced performance when shooting handheld for still subjects or panning and tracking for moving subjects. There is also a customizable AF “return” function for setting the focus position of one’s choice and returning to that preset distance.
The Sigma 500 mm f/4 supports Canon, Nikon and Sigma mounts. The Nikon mounts feature the brand new electromagnetic diaphragm. The lens, in Canon and Sigma mounts, will be available in late October. The Nikon mount will be available in late November.
