The Samyang 12mm T3.1 fisheye lens for Canon EF Mount gives you approximately a 180° view with dramatic results. This lens can be used with a full frame digital camera or 35mm film camera. The fisheye perspective is useful for architectural interiors, landscapes and creative experimentation. With hybrid aspherical lenses, you will produce sharply defined images with a minimum of distortion and chromatic aberrations. The T3.1 aperture is effective in low light situations, and allows for some control over depth of field.
