The Rokinon 16mm F/2.0 ED AS UMC CS Lens for Canon EF-S Mount is a manual focus wide-angle lens compatible with APS-C format DSLR digital cameras. It provides a 79.5deg. angle of view which translates into a 35mm format equivalency of 25.6mm. A fast maximum aperture of f/2.0 is effective in low light shooting and provides shallow depth of field. With two aspherical lens elements and one extra-low dispersion element, chromatic aberrations are minimized and sharp, color-accurate images are the result. UMC lens coating facilitates even light transmission and reduces ghosting and flares.

I bought this lens to enable better night and astro photography. I needed a faster wide-angle lens and I am not disappointed. But you must do a lens test before going out into the dark. The focus wheel is not calibrated very accurately, but that doesn't mean you can't find the sweet spot. This lens is sharper at F/2.0 than I expected! And for that I am very happy!
