| Uniform sharpness and minimal distortion
across the entire image area, even at full aperture, distinguish
this lens. 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 exposure metering are performed
by looking through the camera's viewfinder, whereas the
actual field coverage is checked by means of an accessory
brilliant viewfinder. |
