Leica Vario-Elmarit-SL 24–90 Mm F/2.8–4 ASPH.
Delivery Date : 2 - 3 days
The Leica Vario-Elmarit-SL 24–90 mm 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.
CONSTRUCTION DETAILS
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.
