If you're a big fan of Sigma's latest lenses, the company has just announced new ways to show that love. Sigma has added three new t-shirt designs and one new hoodie. While the t-shirts depict optical formulas, the hoodie design seems... uninspired?
Sigma has included a new all-metal magnetic lens cap (in addition to the normal plastic cap) with its three latest lenses, and the company seems to admit that the meticulously crafted, tested, and machined pieces of metal are a bit over-engineered.
Sigma has announced three new primes in the company's "Contemporary" line of lenses, but has categorized them additionally under what they are calling the "I Series." I Series Lenses are characterized by a compact design mixed with "superb optical performance."
