World's first digital zoom lens with super fast f1.8 aperture. This lens is designed for APS-C size sensors and will vignette at 18mm on full frame cameras. Paired with a proper body you will get a 35mm equivalent of aproximately 28-56mm lens. Optically this lens compares to many fast primes out there. It's very sharp, even wide open, and chromatic aberration and vignetting are very controlled.
