The Leica Universal Wide-Angle Viewfinder enables precise cropping of the subject with the LEICA TRI-ELMAR-M f/4/16-18-21 mm ASPH. on the LEICA M7 and MP as well as the digital LEICA M8. For the LEICA M8, the focal length extension factor of 1.33x has to be considered, so in this case the bright-line frames for 21, 24 or 28 mm are set on the LEICA UNIVERSAL WIDE-ANGLE VIEWFINDER M. A parallax compensation dial enables adjustment of the frame to the focusing distance in five steps.
Thanks to one aspherical lens element and one with achromatic correction, the LEICA UNIVERSAL WIDE-ANGLE VIEWFINDER M is insensitive to stray light and features high resolution and exceptional brilliance. An illuminated spirit level helps to keep the camera horizontal even in unfavorable light conditions. The eyepiece has a screw mount for optionally available diopter correction lenses.
