The Rokinon 8mm Ultra Wide Angle f/3.5 Fisheye CS lens is equipped with a Sony E-mount bayonet and was specifically designed for Sony's NEX and E-mount series. Due to Sony's one-off construction of their NEX and E-mount series, the bayonet mount was carefully adjusted to ensure the widest possible field of vision and to prevent vignetting. Just like in other lenses constructed for filming purposes, aperture adjustment is perfectly smooth. It gives you a 180 degree view with dramatic, exaggerated perspective. With hybrid aspherical lenses and multi-layer coating, you will produce sharply defined images with a minimum of flare and ghosting. The 8mm lens focuses as close as 1' (30.48 cm) from the lens, and has a built-in petal lens hood.
