EDMONTON, CANADA. (November 2009). For available-light photography and thin depth of field, there's no substitute for fast lenses. Here's a test shot from my new Panasonic Leica D Summilux 25mm f1.4, one of the few truly wide-aperture options available for Four Thirds cameras. Somewhat rare, this was a difficult lens to track down. Picture available for sale as prints. Original photo properties: Olympus E-410 dSLR, Leica D Summilux 25mm f1.4 ASPH lens (50mm, 35mm equivalent), handheld, single autofocus, manual exposure, matrix metering, 1/60s f1.4, ISO 100, 2671 x 3535 pixels (after crop), RAW.
