Leica Elmarit-M 90mm f/2.8 - Leica M Mount

The Leica Elmarit-M 90mm f/2.8 (specifically the later 'E46' version) is widely regarded as one of the finest telephoto lenses produced for the M-system. It offers a significant improvement in contrast and sharpness over its predecessors. With a relatively simple four-element design, it provides exceptional clarity and a pleasing bokeh. It is a balanced lens, offering a good compromise between the speed of the Summicron and the weight of the Summarit models. When buying a used Elmarit-M 90mm, check for 'lens creep' or looseness in the built-in telescopic lens hood. The focus throw should be smooth and even; any stiffness may indicate the need for a regreasing of the helicoid. We perform a thorough check for internal haze or 'balsam separation' between cemented elements, which can affect older Leica telephotos. The aperture blades must be dry and snap quickly to the selected setting.
