Leica Summicron-S 100mm f/2 ASPH. Lens

Revolving around a sophisticated optical design, Leica's Summicron-S 100mm f/2 ASPH Lens is a portrait-length prime designed to excel in a wide variety of shooting conditions. Equivalent to an 80mm lens in the 35mm format, this lens is characterized by its fast f/2 maximum aperture for selective focus control and low-light shooting capabilities. The longer-than-normal focal length of the lens contributes to notable subject isolation while providing a natural looking perspective that is well-suited to portraiture applications. In regard to the optical design, a range of low dispersion elements, as well as one double aspherical element, contribute to a marked reduction in chromatic aberrations for greater image clarity and contrast throughout the aperture range.

Dedicated to the Leica S-series of medium-format digital cameras, this lens features an autofocus design along with electronic body-based aperture control. It features an inner focusing mechanism along with a floating element design to enhance close-range imaging capabilities. Housed within a metal barrel, this lens is dust- and weather-resistant to benefit its use in inclement conditions.

• This short-telephoto prime is designed for Leica S medium format cameras and provides a 35mm-equivalent focal length of 80mm.
• Fast f/2 maximum aperture benefits working in difficult lighting conditions and also avails tremendous control over focus for selective focus and shallow depth of field applications.
• Three elements are made from glass with anomalous partial dispersion while another is made from high-refraction extra-low dispersion glass. Together, the combination of these low dispersion elements help to significantly reduce chromatic aberrations and produce greater image sharpness and clarity.
• One double aspherical element works to correct monochromatic aberrations and also reduces the overall weight of the lens.
• Within the seven-elements-in-five-groups optical design, a single floating element independently moves during focusing to ensure greater image quality when working at closer focusing distances.
• Autofocus design benefits from an inner focusing mechanism to maintain the overall lens length during use
• Electronic aperture control is supported via the camera body's control dial.
• Compatible with the Leica S (Typ 006) camera with firmware version 2.4.0.0 or later and the Leica S2/S2-P cameras with firmware version 1.4.0.0 or later.
