Aspherical lenses
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. The universal capabilities of this lens are underlined by homogeneous imaging performance at all focal lengths and distance settings. Only one very light element is moved for focusing. A drive concept comprising a stepping motor and linear positio­ning developed especially for this lens enables very fast, almost-silent and extremely precise focusing. The length of the lens remains unchanged during focusing. The rectangular form of the lens hood supplied with the lens very effectively suppresses undesirable reflections and stray light. Robust and resilient construction, impermeable seals and AquaDura
®
coating of exposed glass surfaces make the lens ideal for use in even the toughest working con-
ditions.
