Sigma Turns 50 and Celebrates With Giveaways

50 years is a ripe old age for a business, and a mark well worth celebrating. Sigma's doing just that, by launching a special 50th anniversary site and giving away gear, like the soon-to-be released SD1.

In addition to giveaways, the site offers more information about the Sigma company, advice from professional photographers, and more.

"It's an honor to share this moment with Sigma users and to give them something in return for their unwavering support," says Sigma president Mark Amir-Hamzeh. "We hope our fans will check back regularly to see what we have planned and to enter to win some of our most exciting products."
