Outlet Vario-Elmarit-SL 24-90mm f/2.8-4 ASPH. Lens Zoom Lenses

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.
