Descriptions:

The Leica Universal Wide-Angle Viewfinder M 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 for21, 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.

A new design of the interior focusing significantly enhances the
quality in the close-focus range through an adaption of the floating element
principle. Brilliant field depth can therefore be used from a distance of 0.33m
for hyperfocal photography. Save money by buying the lens in a set together
with the Universal Wide-angle Viewfinder M. (included in this version).
