The non-weather-sealed version of the lens is imminent.
The third-party lensmaker's new supertelephoto won't cost much more than an earlier 200-500mm model with no image stabilization.
When it ships, the new lens will offer long-range sports and wildlife shooters some new competition, but it's not as fast a supertele as some rivals.
Have an X-mount camera? Here's what you have to look forward to.
The G3 X is slated to have a 1-inch sensor and a 25x zoom lens.
After 16 years, the versatile but elderly telephoto zoom now has a successor. The new 100-400mm lens has better optics and image stabilization, along with a higher price.
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.
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.
Pros and enthusiasts in the US can rejoice that many of Canon's SLR lenses are a notch less pricey now. Better exchange rates might deserve some of the credit.
The TG-3 is just as tough as its predecessor, but gets a cool new macro trick and accessory, while the 24x compact zoom SH-1 gets styling and image stabilization to match the company's interchangeable lens cameras.
