By exerting superiority in mirrorless camera-dedicated designs, the lens size and weight are successfully reduced, while achieving uniformity and high resolution from the centre to the periphery throughout the zoom range. Furthermore, compatibility with the latest mirrorless camera bodies and functions assists in various photographic environments and meets the high demands of professional or advanced amateur photographers. Following 14–24mm F2.8 DG DN | Art, 24–70mm F2.8 DG DN | Art has appeared as the flagship of the new-generation Art zoom and ultimate large-aperture standard zoom lens.
Best-in-class optical performance
The F2.8 Art zoom flagship zoom lens series is developed primarily to achieve superior optical performance. As extra-low dispersion glass materials, six sheets of “F” low dispersion (FLD) glass and two sheets of special low dispersion (SLD) glass are lavishly employed while taking advantage of an optical design dedicated for mirrorless lenses. By employing three aspheric lenses, this zoom lens thoroughly subdues aberrations such as axial chromatic aberration or sagittal coma aberration, which are difficult to correct in post-processing, tailors the resolution and achieves uniformity and superior optical performance from the centre to the periphery throughout the zoom range. In addition to Super Multi-Layer Coating, Nano Porous Coating* is employed. This lens is designed so as to be less affected by strong incident light such as flare. The mirrorless camera-dedicated design successfully contributes to reduction in the lens size and weight.
Ensuring compatibility with the latest full-frame mirrorless camera bodies
The SIGMA 24–70mm F2.8 DG DN ensures compatibility with various types of the latest full-frame mirrorless camera bodies so as to be capable of exerting the best performance under any photographic circumstances, assuming that professional or advanced amateur photographers use it. To the AF-L button, for example, various functions can be assigned from a camera body, which enhance the operability while photographing. Employing a stepping motor and the latest algorithm successfully establishes a good balance between acceleration and quietness of the AF drive.
Adaptable to various uses and photographic environments
In consideration of shooting under challenging shooting conditions, the dust- and splash-proof structure and water- and oil-repellent coating are adopted. In addition, a variety of functions, such as an AF-L button that can assign various functions to the lens barrel, a zoom lock switch that is unlocked by zoom operation, a nice touch AF / MF switch, are featued.
About the shortest shooting distance
The minimum focusing distance is 18 cm at the wide-angle end. This allows you to come closer to a subject than the end of a hood to take photographs. The maximum magnifications are 1:2.9 at the wide-angle end and 1:4.5 at the telephoto end, which provides a wider range of expression by close-up photography.
Designed to minimise flare and ghosting
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. In addition to Super Multi-Layer Coating, Nano Porous Coating is employed. These coatings reduce flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.
Rounded diaphragm (11-blade)
The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
