Sigma has added two new fast-aperture lenses to its Art and Contemporary lineups. 

For owners of Canon, Nikon and Sigma APS-C bodies there's the 50-100mm F1.8 DC HSM Art, which is equivalent to 75-150mm. This lens has a redesigned Hyper Sonic Motor, nine-blade rounded aperture and internal zoom. Being a weighty lens (1490g/3.3lbs), it also has a built-in tripod socket.

The other lens falls into Sigma's 'Contemporary' lineup and is for Sony E-mount and Micro Four Thirds bodies, and it's a fast 30mm F1.4 prime, equivalent to 45mm and 60mm, respectively. This lens uses a stepping motor for fast and quiet focus during video and weighs just 263g/9.3oz. 

The 30mm F1.4 will ship in mid-March at an MSRP of $339, while the 50-100mm F1.8 is expected in late April priced at $1099.

Tested for Optimum Performance

Sigma lenses are born of well-thought-out design concepts, exceptional Japanese craftsmanship and manufacturing, and advanced lens performance testing and evaluation. To this end, Sigma has developed its own A1 proprietary MTF (modulation transfer function) measuring system using 46-megapixel Foveon direct image sensors. Even the most elusive high-frequency details are within the scope of Sigma’s quality control inspections. Every Global Vision lens is A1 tested, analyzed and approved before leaving the factory ensuring maximum performance out of the box.
