Get the big picture — indoors
Say you're at the society event of the season, and you've been asked to document the event. The locale? A large, high-ceilinged hotel ballroom downtown, complete with a stage that houses a 19-piece big band. Oh, yeah, it's also pretty dark. How do you show people the scope of the place? How do you show people having fun without putting a flash unit in their faces?
Time to consider one of the most light-sensitive wide-angle lenses available today: the Sigma Photo 20mm f/1.8 lens. With its wide aperture that's perfect for low-lit interiors, you'll be snapping away in seconds, and, if you're shooting on a full-frame camera, everyone will get an idea of the grandeur and scale of what's going on. Even on an APS-C camera, you'll have a wide-angle 30-32mm focal length. Plus, the lens is perfect for landscapes and architectural photography as well, as you'll be able to fit a lot into one frame. Features like aspherical lens technology and a rear focusing system ensure that your images will have minimal color fringing and deliver solid image quality across the entire frame.
