Sigma Celebrates 50th Anniversary at WPPI With Coupons and Giveaways

New companies come and go, but some of them stick around for a good long while. Sigma is one of them, and is celebrating its 50th anniversary at the Wedding & Portrait Photography International expo this week.

"We view this anniversary celebration as both a tribute to what we've accomplished in the last five decades and as a fete of what's to come in the years ahead," says Sigma president Mark Amir-Hamzeh.

The folks at Sigma are giving out $50 coupons, golden tickets good for a Sigma 50mm F1.4 EX DG HSM lens, and giving booth visitors a chance to meet pros like Kevin Ames and Lindsay Adler.

You can even get yourself a free T-shirt just for stopping by and telling Sigma reps why you love the company.
