Leica Thambar-M 1:2.2/90
(Photography Blog)

The Leica Thambar-M 1:2.2/90 is a specialised soft-focus telephoto lens for Leica M-mount cameras. Its focal length of 90 mm is suitable for photography in a multitude of scenarios and is as good as predestined for capturing portraits with a uniquely aesthetic atmosphere that cannot be reproduced in digital postprocessing. The optical formula comprises 4 elements in 3 groups and 20-bladed iris diaphragm diaphragm that allows the lens to deliver a unique bokeh with perfectly round rendition of point light sources. The soft look of the Thambar is the result of intentionally accepted under-correction of spherical aberration. This under-correction increases towards the edges of the optical system with the consequence that not only the depth of focus, but also the degree of softening can be precisely controlled by means of the stepless aperture setting. The Leica Thambar-M 1:2.2/90 will be on sale from mid-November 2017.
