Lens Hood supplied

Designed and constructed exclusively by Leica, the central shutter available for all S lenses is not only especially compact and efficient, but also has a guaranteed service life of at least 100,000 shutter cycles, making it extremely reliable.

The Leica S-System features a dual shutter concept. This means that photographers can choose the shutter system to meet their needs and the particular situation before every shot. The camera body is constructed with a metal focal plane shutter offering a top speed of 1/4000 of a second and flash sync at 1/125. The main switch on the S2 camera body allows users to change rapidly to central shutter use as soon as a CS lens is mounted. With a top speed of 1/1000 of a second, the central shutter offers a working range expanded by three f-stops. This means that users have considerable more scope for creative lighting such as studio flash systems, which might be used to suppress ambient light or to create fill light in bright surroundings at larger lens apertures. Thanks to the seamless integration of the central shutter function in the cameras electronics, photographers can switch rapidly between the two shutter systems at any time.

This standard lens, available with or without a central shutter, gives priority to top imaging performance for all applications. In addition to an aspherical surface, special glass with anomalous partial dispersion or high refractive power is used. Focusing combined with a floating element provides consistent high contrast performance through the entire working range, from close-up to infinity.
