Due to the minimal distortion and barely perceptible field curvature,
it can be recommended for highly demanding architecture photography
even at the 16 mm setting. Used on the digital M8, it produces the
image effect of a 21 - 28 mm lens, still enabling extreme wide-angle
The ultra compact shape is achieved by two aspherical elements. 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 0.33 m for hyperfocal photography. Save money by buying the lens in
a set together with the Universal Wide-angle Viewfinder M.
The LEICA TRI-ELMAR-M 16-18-21 mm f/4 ASPH. will be available from the
End of December 2006.
