The Samyang 8mm Ultra Wide Angle f/3.5 Fisheye Lens for Nikon gives you a dramatic 180deg. view with a greatly exaggerated perspective when used with an APS-C camera. This fisheye lens includes a special chip that allows the lens to work with the camera's focus confirm, auto exposure, auto metering and auto white balance functions. Hybrid aspherical lenses and multi-layer coating help you to produce sharply defined images with a minimum of flare and ghosting. The lens focuses as close as 1' (30.48 cm) from the lens and has a built-in petal lens hood.
