In a brief note on its Japanese website, Sigma has announced that it will be releasing its highly-regarded 35mm F1.4 DG HSM 'Art' lens in Sony and Pentax mounts on 31st May. It's also announced that the Nikon-mount version of its 120-300mm F2.8 DG OS HSM 'Sports' telephoto zoom will go on sale at the same time. We gave the 35mm F1.4 our Gold Award when we reviewed it back in December, for its combination of exceptionally good optics and solid build at a price rather lower than the camera manufacturers' equivalents.
