It's is a compact, lightweight wide-angle lens for APS-C cameras and it's surprisingly versatile. At just 220g and $590, is it worth it? I tested it on the streets of New York, indoors, and on test charts to see how the image quality holds up. We're talking sharpness, bokeh, chromatic aberration, distortion, flaring, and how it stacks up against the Sony version that costs $500 more. Spoiler: it's really good.
