SUPER-VARIO-ELMAR-SL 16-35 mm f/3.5-4.5 ASPH., black

Well-suited for landscape, architecture, and group portrait applications, the Super-Vario-Elmar-SL 16-35mm f/3.5-4.5 ASPH. from Leica is a versatile wide-angle zoom designed for full-frame L-mount mirrorless cameras. The aperture ranges between f/3.5 and f/22 at 16mm or f/4.5 and f/22 at 35mm. Lens delivers an exceptional image quality throughout the entire range of focal lengths, as well as super-fast and quiet autofocus. The Leica Super-Vario-Elmar-SL 16-35 f/3.5–4.5 ASPH is made of 18 lenses in 12 groups. It has the working range from 250mm to infinity Complementing the flexible wide-angle design is a sophisticated optical layout that utilizes a pair of aspherical elements and three low dispersion elements to reduce spherical and chromatic aberrations throughout the zoom range in order to realize a high degree of sharpness, clarity, and color accuracy. Floating elements system maintains consistent imaging quality throughout the focusing range Wide-angle zoom is designed for full-frame, however can also be used with APS-C models where it provides a 24-52.5mm equivalent focal length range. Multi-layer coatings have been applied to individual elements to suppress surface reflections, flare, and ghosting for increased contrast and color fidelity. Stepping motor delivers quick, precise, and near-silent autofocus performance to suit both photo and video applications. This system also avails full-time manual focus override. Water-repellent AquaDura coating has been applied to the front and rear optical surfaces to protect against moisture and other elements. Weather-sealed design protects against dust and moisture to benefit working in inclement shooting conditions. Due to the front lens coating and the barrel that doesn’t extend when zooming, the lens is made to endure a variety of weather conditionsField angle (diagonal, horizontal, vertical)  :                                                      Focal length 16mm: 105,6°/95,3°/72°Focal lenght 24mm: 84,7°/74,4°/53,7°Focal length 35mm: 64,6°/55,5°/38,7°Optical designNumber of lenses/groups: 18/12Number of aspherical lenses:  2Entrance pupil position:                                                                                     Focal lenght 16mm: 105,9mmFocal lenght 24mm: 101,5mmFocal lenght 35mm: 105,0mmWorking range :  250mm to infinitySmallest object field :   Focal length 35mm: 90 x 135 mmLargest reproduction ratio:   Focal length 16mm: 1:7,7, Focal length 35mm: 1:3,7ApertureSetting/function    Electronically controlled aperture, set using turn/push wheel on camera, including half valuesAperture setting range  Focal length 16mm: 3,5-22 Focal length 35mm: 4,5-22Lowest value    22Bayonet/sensor format   Leica L bayonet, full-frame 35mm formatFilter mount    E82Length to bayonet mount 123 mm (without lens hood)Largest diameter    88 mmWeight  990 g
