Best-in-class performance and large-aperture standard zoom lens that offers high resolution throughout the entire zoom range.
Best performance can be provided due to a large-aperture zoom. This creed made an extremely high sense of resolution achieved in 14-24mm F2.8 DG DN | Art, the SIGMA’s first Art zoom dedicated for mirrorless cameras. It is also inherited in 24-70mm F2.8 DG DN | Art, the second Art zoom. 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.
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.
Adaptable to various uses and photographic environments
The lens adapts to various uses and usage environments through employment of the dust- and splash-proof structure and the zoom lock mechanism for preventing the lens barrel from extending unexpectedly, and meet a wide range of needs for photography. An AF/MF switch used for the many conventional SIGMA’s lenses is also embedded in the lens barrel. Essential and basic functions are also equipped.
The lens body is elaborately made in detail. Its operating parts such as a zoom ring and manual ring are nice to the touch.
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 minimize 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. SIGMA’s Super Multi-Layer Coating reduces 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.
High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
