Compact for travel, it's light enough to carry 24/7. And that big maximum aperture delivers a blindingly bright finder image. Want more? Even the expensive ones are a bargain. Compare, for example, Nikon's 50mm f/1.4, at $290 (street), to its 85mm f/1.4, which costs $1,000. No wonder every pro we know owns a 50mm f/1.4.
