The DA Limited’s are a trade off. Compact size, light weight, exceptional build quality, beautiful manual focus handling - at the expense of a half stop or a full stop of light. The aperture size is still aligned to be larger than most of what would be needed to capture an image with a specific focal length. They aren’t slow. Even the DA 21 is f/3.2 wide open (not far off f/2.8). The DA 15 is the slowest of the bunch at f/4 but would normally be used around f/8. These lenses are the Spartan warriors of the digital lens world.
