Leica Tri-Elmar-M 16-18-21mm 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 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 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 field depth can therefore be used from a distance of 0.33 m for hyperfocal photography.
The Universal Wide-Angle Viewfinder M enables precise cropping of the subject with the Leica Tri-Elmar-M 16-18-21 mm f/4 ASPH. It is insensitive to stray light and features high resolution that result in brilliant pictures and vivid colors. This viewfinder is fit for both analog and digital Leica M-Cameras.
A parallax compensation dial enables adjustment of the frame to the focusing distance in five steps. One aspherical lens element and one with achromatic correction enable high resolution. 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.
