From barely digital to seriously high tech, it was a surprisingly good year for camera fans.
A wide angle zoom, portrait and supertelephoto will arrive starting in October.
The company's new Cine lenses are designed with Sigma's characteristic classic touch, and most are designed for use with full-frame cameras.
The company's entrance into the pro video lens market is comprised of core lenses, most of which are optimized for full-frame rather than Super 35.
LIke its enthusiast compacts, Sigma's Foveon-based interchangeable-lens models are kind of odd.
In addition to a 30mm f1.4 that Sigma says is affordable and a 50-100mm f1.8, the company also introduces an intelligent Canon-to-Sony-E-mount converter.
Need some inspiration? Try one of these lenses, available for less than $1,000, £700 or AU$1,400 for a change of pace.
The new 20mm f1.4 Art, designed for higher-resolution cameras, is the fastest full-frame wide-angle to date.
A reasonable price for this fast, wide-angle zoom.
The non-weather-sealed version of the lens is imminent.
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 company adds a 24mm f1.4 to its excellent lens portfolio.
