Leica Vario-Elmarit SL 24-90mm f2.8-4 ASPH Lens
The Leica Vario-Elmarit-SL 24–90mm f/2.8–4 ASPH. is very fast and offers a large range of focal lengths. A close focusing limit of 0.3 meters at its wide-angle setting and a maximum reproduction ratio of 1:3.8 at the telephoto end of the zoom range provide fascinating opportunities. Its optical image stabilisation (OIS) compensates for up to 3.5 stops of camera shake.
With its wide range of focal lengths and high speed, the Leica Vario-Elmarit-SL 24-90 mm f/2.8-4 ASPH. is the ideal standard zoom lens in the Leica SL-System portfolio. This completely new design with internal focusing and integrated optical image stabilisation is impressive with its excellent imaging performance at distances from 30 cm to infinity, both at maximum aperture and stopped down. A total of 18 elements in six moving groups are employed to achieve the outstanding optical performance of this lens. In addition to four aspherical elements, the design of this lens also features eleven elements made from glasses with anomalous partial dispersion for the correction of chromatic aberrations.
Of the 18 elements in six moving groups, four are aspherical lens elements and 11 are elements made from glasses with anomalous partial dispersion for the correction of chromatic aberrations. Only one very light element is moved for focusing. Very fast, almost-silent, precise focusing is enabled by a specially developed drive concept comprising a stepping motor and linear positioning. This means that the overall length of the lens does not change during focusing. The rectangular form of the lens hood supplied with the lens very effectively suppresses undesirable reflections and stray light and prevents flare.
