Lens Description: The Sigma 18-35mm f/1.8 DC HSM is the first zoom lens ever to achieve a maximum aperture of f/1.8 throughout the zoom range. It is a wide aperture, standard zoom-lens for digital single lens reflex cameras with APS-C size sensors. The lens has a focal range equivalent to 27mm - 52.5mm in a 35mm format and it can cover the angles of view of multiple fixed focal length lenses. This wide aperture, standard zoom lens enables the photographer to expand creative possibilities on any occasion.
Photography Life Review Summary: Overall, I am very impressed by the performance of the Sigma 18-35mm f/1.8 DC HSM. It is certainly a game changer, not only because it is the first f/1.8 zoom lens in history, but also because it is a stellar performer. I cannot wait to see more lenses like this from Sigma in the future. If I owned a DX / APS-C camera, the Sigma 18-35mm f/1.8 would have been one of my first candidates for everyday photography.
