Sigma is set to launch new 30mm and 50-100mm lenses.

Sigma will use the opening day of the CP+ Camera & Photo Imaging show, in Yokohama, Japan to unveil the Sigma 30mm f/1.4 DC DN and 50-100mm f/1.8 DC HSM.

The 30mm f/1.4 prime lens, due out next month is Micro Four Thirds and Sony-E-mount, should deliver the 35mm viewing-angle equivalent of 60mm on micro-four-thirds cameras; and 45mm on a Sony E-system model.

The £239.99 lens – which extends Sigma’s Contemporary range – features two aspherical elements, a nine-blade diaphragm and a stepping motor to help bring fast and quiet AF to videographers.

Sigma has also today unwrapped the 50-100mm f/1.8 DC HSM, due out in Sigma, Canon and Nikon mounts at a date yet to be announced.

Priced £779.99, the APS-C-format zoom forms part of Sigma’s Art line-up and aims to cover the focal lengths of ‘three prime lenses in one’.

The nine-blade diaphragm lens boasts a redesigned Hyper Sonic Motor (HSM) which is 30% slimmer than in previous models, according to Sigma.
