I'm in the market for an f1.4 or f1.8 digital camera. I'm tired of logging my DSLR around, but I refuse to settle for a regular point and shoot. I often shoot in low light conditions, don't care for depth of field and prefer no flash. Right now my DSLR has an f1.4 USM 50mm lens, which I'm very happy with. I want a smaller version of that. Does anyone have any suggestions? Price limit: up to a thousand.
