The zoom range of the fast Leica APO-Vario-Elmarit-SL 90–280 mm f/2.8–4 follows on directly from that of the Leica Vario-Elmarit-SL 24–90 mm f/2.8–4 ASPH. Together, these two lenses cover a range of focal lengths exten­ding from 24 to 280 mm. This completely new telephoto lens construction features double internal focusing, in which two lens elements move towards each other. This guarantees extremely fast and almost-silent autofocus and consistently high imaging performance from infinity to its closest focusing distance. This zoom lens with apochromatic correction resolves the finest structures without color fringing and with very high contrast rendition at all settings. Of the 23 elements in seven moving groups, seven are made from glasses with anomalous partial dispersion for the minimization of chromatic aberrations. A special feature of this is that the overall length of the lens does not change when either focusing or zooming. The lens hood supplied with the lens suppresses undesirable reflections and stray light and prevents flare. The lens also has a removable tripod plate for attaching it to a tripod.
