Together, these two lenses cover a full range of focal lengths extending from 24 to 280 mm.\u003cbr\u003eThe newly developed dual internal focusing (DSD®) concept enables a fast autofocus. Its optical image stabilisation (OIS) compensates for up to 3.5 stops of camera shake.\u003cbr\u003e\u003cbr\u003eThe autofocus system shared by these lenses is fast, precise, and nearly silent. Their outstanding AF performance figures are thanks to the autofocus drive unit they both utilize. These are limited only by the mass of the glass elements moved when focusing; the speed of moving from infinity to the closest focusing distance. In order to preserve the compact dimensions of the lenses, the integration of these components must be perfectly optimized within all design constraints. \u003cbr\u003e\u003cbr\u003eSpecialists from the areas of optical engineering, mechanical engineering and electronics worked together as an interdisciplinary team on the development of a unique lens concept based on double internal focusing. This system, comprising two especially light focusing lenses, allows the construction of particularly small and compact drive systems. While being able to work within tight space constraints, the drive motors used must maintain peak performance in all situations to be chosen for such a cutting-edge camera system.\u003cbr\u003e\u003cbr\u003eSeveral contrast measurements at various focusing positions must be made before the correct direction for focusing can be determined and followed by precise focusing. In this procedure, the focusing lens elements must be moved rapidly in accordance with the speed specifications of the contrast AF system. This requires a dynamic drive system without any room for error.\u003cbr\u003eIn these lenses, the drive units installed are extremely powerful and robust stepping motors with Dual Syncro Drive™. Thanks to these, the entire focusing range can be traveled completely in fractions of a second. This means that the  lenses achieve values that are among the best in the full-frame system segment in terms of speed, precision, and operating noise. \u003cbr\u003e\u003cbr\u003eOf the 23 elements in seven moving groups, seven are made from glasses with anomalous partial dispersion for the minimisation of chromatic aberrations. The movement of the two focusing elements is provided by a newly developed drive concept with linear positioning of the lenses by stepping motors. A special feature of this is that the overall length of the lens does not change when either focusing or zooming. \u003cbr\u003e\u003cbr\u003eThe lens hood supplied with the lens suppresses undesirable reflections and stray light. The lens also has a removable tripod plate for attaching it to a tripod. Its ergonomic design makes the lens easier to carry by hand and allows the attachment of a lens belt. A lockable rotating tripod collar allows the lens to be fixed at any angle. The collar has detents every 90 degrees for rapid switching from landscape to portrait format.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003e\u003cspan style=\"font-size:
