The 50mm delivers sharp photos at almost all apertures.
Under CEO Kazuto Yamaki, Sigma has helped transform the Japanese company so most of its revenue comes from higher-end products. Too bad about the camera business, though.
Not to be left behind in the supertelephoto zoom department, Sigma literally one-ups one of its main rivals with the announcement of two different 150-600mm zoom designs.
The revised 18-200mm f3.5-6.3 macro lens sports the same fit and finish as Sigma's latest models.
Featuring the same focal length as a popular model from Canon, the new Sigma 24-105mm lens looks as though it will be a fierce competitor to the old workhorse.
While it's not cheap, the Sigma 50mm f1.4 lens provides great value for the money.
The trio of Foveon-based cameras announced in February are priced similarly to their predecessors.

The lens manufacturer has launched its Mount Conversion service, which will let you update any of its newer lenses to a compatible mount on demand.
The company brings its 18-200mm macro and 50mm f1.4 lenses up-to-date for 2014.
The general-purpose zoom lens costs about $100 more than Canon's equivalent, but Sigma thinks its image quality means the lens is worth the extra money.
