The non-weather-sealed version of the lens is imminent.
The company adds a 24mm f1.4 to its excellent lens portfolio.
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.
In addition to notable lenses from Canon, Sigma, Pentax and more, Olympus revealed development plans for a pro 8mm f1.8 fisheye. Look out for updates if any more announcements come from the upcoming CP+ 2015 show.
The trio of Foveon-based cameras announced in February are priced similarly to their predecessors.
