The 8mm Ultra Wide Angle f/3.5 Fisheye Lens for Canon Mount from Samyang gives you a 180° view with dramatic, exaggerated perspective. With a hybrid aspherical lens and multi-layer coating, you can 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.
