This lens is distinguished by uniform sharpness and minimal distortion across the entire image area even at full aperture. This was achieved with, among other factors, a lens element with an aspherical surface. The lens makes highly dramatic effects possible, like monumental foregrounds, strongly receding backgrounds and a wide horizon. With this lens, focusing and metering are performed by looking through the camera's viewfinder, while the actual framing is checked with an optional accessory viewfinder #12008 that mounts in the camera's hot-shoe.
Compact wide-angle lens with an aspherical lens surface for excellent optical performance
