The super wide-angle lens with three focal lengths
Perfect performance even in close-focus range
With its impressive angle of view of 107°, this lens conquers 16mm 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 16mm setting. The Tri-Elmar-M 16-18-21mm f/4 ASPH. unites three super wide-angle focal lengths in one compact lens.
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 0.33m for hyperfocal photography.
The Leica Tri-Elmar-M 16-18-21mm f/4 Aspherical Lens gives incredible versatility & optical brilliance to the Leica shooter who doesn't need the higher speed of the single-focal-length lenses. The Tri-Elmar is not a zoom, but a three-focal-length lens offering 16mm, 18mm and 21mm choices with a simple twist. Due to the minimal distortion and barely perceptible field curvature, it can be recommended for highly demanding architecture photography even at the 16mm setting. Used on the digital M8, it produces the image effect of a 21 - 28 mm lens, still enabling extreme wide-angle views.
This lens has been updated with the "6-bit" coding, which allows the digital M camera to read this information optically and to identify which lens is being used. The camera can then (optionally) apply a "final stage" software-based vignetting correction (for RAW images the lens used is simply recorded, no change is made).
