LEICA TRI-ELMAR-M 16-18-21 mm f/4 ASPH.
With its impressive angle of view of 107?, this new TRI-ELMAR conquers 16 mm super wide-angle photography in perfect Leica M style. Due to the minimal distortion and barely perceptible field curvature, it can be recommended for highly demanding architec- ture photography even at the 16 mm setting. Used on the digital M8, it produces the image effect of a 21 - 28 mm lens, still enab- ling extreme wide-angle views. 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 depth of field 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.

Relative Distortion
The MTF is indicated at full aperture and at
f/5.6 and f/8.0 at long taking distances (infinity). Shown is the contrast in percentage for 5, 10, 20 and 40 lp/mm accross the height of the 35 mm film format, for tangential (dotted line) and sagittal (solid line) structures, in white light. The 5 and
10 lp/mm will give an indication regarding the contrast ratio for large object structures.The 205and 40 lp1/0mm reco1r5ds the re2s0olution of finer and finest object structures.Y'[mm]

Distortion is the deviation of the real image height (in the picture) from the ideal image height. The relative distortion is the percentage deviation.
The ideal image height results from the object height and the magnification. The image height of 21.6mm is the radial distance between the edge and the middle of the image field for the format 24mm x 36mm. The graph of the effective distortion illustra- tes the appearance of straight horizontal and verti- cal lines in the picture.
Vignetting is a continous decrease of the illumina- tion to the edges of the image field. The graph shows the percentage loss of illumination over the image height. 100% means no vignetting.
