Sony full-frame fans rejoice - Sigma president says company is going to support FE-mount! I'm a huge fan of Sigma. Their 30/1.4 crop sensor lens is one of my favorites. It's nice to see they will eventually produce lenses in FE mount. They also have an interesting motto, something along the lines of "small office, big factory." Unlike some other manufacturers, they produce as much as they can in-house to save costs. They use their own cameras (Merrill, Quattro, etc.) as measurement tools for their lenses. IMHO, they're the first independent lens manufacturer to give the big boys a real run for their money.
