- The lenses use Sigma's updated Hyper Sonic Motor for quicker autofocus
- Nikon version uses an electronic diaphragm to provide accurate exposure during high-speed shooting
- The lenses are intended for full-frame digital cameras
Sigma has unveiled a trio of lenses that could find appeal among three very different groups of photographers.
The three lenses – 85mm f/1.4 DG HSM Art, 12-24mm f/4.0 DG HSM Art and 500mm f/4.0 DG OS HSM Sport – are part of Sigma’s Global Vision series.
The lenses are available in three mounts – Canon EOS, Nikon F and Sigma – and can be adapted to the Sony E-mount via Sigma’s own MC-11 converter.
These are “DG” lenses, which means that they are compatible with full-frame Canon and Nikon bodies. They also can be used with cameras that are fitted with an APS-C sensor, when the camera’s sensor crop should be taken into consideration.
The firmware of all three lenses can be updated via Sigma Optimization Pro and the Sigma USB Dock.
12-24mm f/4.0 DG HSM | Art, US$1,599
This ultrawide-angle zoom uses 16 elements in 11 groups and includes FLD glass elements. There are nine aperture blades, and the Nikon version uses an electronic diaphragm for accurate exposure during high-speed photography.
The maximum aperture is f/4.0 throughout the zoom range.
Sigma says that it has updated the Hyper Sonic Motor that provides 1.3 times the amount of torque of previous lenses, which should provide for faster autofocus.
This lens is not able to accept filters because of the large bulbous front element. A petal lens shade is included, which should help to protect the lens against impact damage.
Sigma says edge-to-edge performance was very important when it designed the 12-24mm lens.
Its close-focus distance is 9.5 inches (24cm).
The lens is 4 x 5.2 inches (102 x 131.5mm) and weighs 2.5 pounds (1.2 kilograms).
The 12-24mm will be available in late October.
85mm f/1.4 DG HSM | Art, US$1,199
The other Art series lens is a high-speed portrait lens.
The 85mm f/1.4 DG HSM Art has 14 elements in 12 groups, including two FLD (performance equal to fluorite) glass elements and one element with “a high rate of anomalous partial dispersion and high refraction.”
This lens uses the updated Hyper Sonic Motor that provides 1.3 times the amount of torque of previous lenses for fast autofocus.
The 85mm lens uses nine aperture blades, and the Nikon mount lens uses an electronic diaphragm for accurate exposure during high-speed shooting.
It has a close-focus distance of 33.5 inches (85cm), and it uses 86mm filters. A petal lens shade is included.
The lens is 3.7 x 5 inches (94.7 x 126.2mm). Its weight hasn’t been announced.
The 85mm is expected to begin shipping in late October.
500mm f/4.0 DG OS HSM | Sport, US$5,999
With a price tag of nearly US$6,000, this won’t be an impulse buy, and it likely caters to sports and wildlife photographers who want a premium optic.
Sigma touts the durability of this long telephoto lens. It has magnesium alloy components, a carbon fiber lens shade, a coating on the front element that resists oil and water. The lens also is sealed against dust and moisture.
The 500mm lens uses 16 elements in 11 groups, including two FLD and one SLD glass elements. There are nine aperture blades, and the Nikon version uses an electromagnetic design that allows the aperture blades to snap open and closed for high-speed shooting.
The lens uses Sigma’s upgraded Hyper Sonic Motor, which has 1.3 times the torque of previous lenses. That contributes to faster autofocus. Its close focus distance is 11.5 feet (3.5 meters).
The 500mm lens can be paired with Sigma’s TC-1401 1.4X and TC-2001 2X teleconverters, which results in an effective focal length of 700mm and 1,000mm, respectively. There are two stages of image stabilization. One is for handheld shooting, and the other is for panning.
With a lens this long, a tripod collar is welcome and included. 46mm filters can be used on the rear of the lens. The lens comes with a Sigma Weather Resistant (WR) Protector filter that is attached to the front.
The 500mm lens is 5.7 inches x 15 inches (144.8 x 380.3mm) and weighs 7.3 pounds (3.3 kilograms).
The Canon and Sigma mounts will be available in late October, while the Nikon version will ship in late November.
