The Rokinon 14mm f/2.8 IF ED MC Super Wide Angle Lens for Pentax gives you approximately a 115deg. view with dramatic results when used with a full frame digital camera or 35mm film camera. With hybrid aspherical lenses, you will produce sharply defined images with a minimum of distortion and chromatic aberrations. This manual focus 14mm lens focuses as close as 0.9' (0.27m) from the lens and has a built-in petal-type lens hood. With some cameras, Shutter Lock must be disengaged on the camera's menu.
