Sigma has released a slew of new lenses – four to be exact, namely a 14mm f/1.8 DG HSM Art, 135mm f/1.8 DG HSM Art, 24-70mm f/2.8 DG HSM OS Art and a 100-400mm f/5-6.3 DG HSM OS Contemporary.
According to Sigma, the 14mm is the first full-frame ultra-wide with an f/1.8 aperture and incorporates a large aspherical front element, three FLD (“F” Low Dispersion) elements and four SLD (Special Low Dispersion) elements which all work together to reduce distortion, produce better edge-to-edge sharpness and reduce chromatic aberration.
Next up is a new 135mm f/1.8 DG HSM Art, which also features a very wide f/1.8 aperture and a newly-designed larger hyper sonic motor (HSM) which provides more torque and speed when the lens is autofocusing.
The next lens is the 24-70mm f/2.8 DG HSM OS Art, which is a revamped version of a previous zoom lens.
The new 24-70mm has been improved optically and includes three SLD (Special Low Dispersion) glass elements and four aspherical elements to reduce chromatic aberration.
It’s also built-in with Sigma’s optical image stabilisation technology.
Last, but not least is the 100-400mm f/5-6.3 DG HSM OS Contemporary lens, which is a long telephoto zoom that covers a popular range of focal lengths suitable for sports and wildlife photography.
Sigma has also included a redesigned optical image stabilisation and autofocus system in the 100-400mm so that it performs better in these situations.
The four lenses will be available in Canon, Nikon and Sigma mounts while Sony users will have to use an adaptor to convert the lens to the E-mount system for Sony mirrorless cameras.
Local availability and pricing have yet to be determined.
