Sigma 50mm f/1.4 DG HSM Art Lens To Be Released In May 2014 (?)
A reader of Photo Rumors visited The Photography Show in Birmingham, UK, and asked the Sigma staff when their new 50mm f/1.4 DG HSM Art will be available for the public. The answer was: the lens will probably released in two months. That’s May 2014.
The Sigma 50mm f/1.4 is Sigma’s latest lens in the “Art” line-up, and I am sure it will be another outstanding lens. Sigma aims at the Zeiss Otus 55mm f/1.4 with the with their new 50mm f/1.4 lens. The Sigma was presented at CES 2014.
The Sigma 18-35mm f/1.8 Art (see coverage here) and the Sigma 35mm f/1.4 DG HSM (see coverage here) are good examples of recent, excellent lenses made by Sigma.
