Sigma 24-70mm f/2.8 DG DN Art Lens for Sony E Full-Frame Mirrorless Cameras

The 24-70mm f/2.8 DG DN Art Lens from Sigma is a large-aperture standard zoom for full-frame mirrorless camera based on E-mount systems. It features a sophisticated optical design that delivers high resolution throughout the entire zoom range.The Sigma 24-70mm F2.8 DG DN | art lens is the second newly-designed “art zoom” dedicated for mirrorless cameras. Best-in-class performance and large-aperture standard zoom lens that offers high resolution throughout the entire zoom range.For Professional and Advanced Amateur PhotographersThe Sigma 24-70mm f/2.8 DG DN Art lens exerts superiority in mirrorless camera-dedicated designs, resulting in a reduced lens size and weight while achieving uniformity and high resolution from the center to the periphery throughout the zoom range. Compatibility with the latest mirrorless camera bodies and functions assists in various photographic environments and meets the high demands of both professional and advanced amateur photographers.Superior Optical PerformanceThe f/2.8 Art Series Lens is developed to achieve superior optical performance. By employing three aspheric lenses, this zoom lens thoroughly subdues aberrations such as axial chromatic aberration or sagittal coma aberrations, which are difficult to correct in post-processing, tailors the resolution and achieves uniformity and superior optical performance from the center to the periphery throughout the zoom range. In addition to Super Multi-Layer Coating, Sigma’s proprietary Nano Porous Coating is employed to achieve high-contrast and clear image quality. This lens is designed to be less affected by strong incident light such as flare.Flexibility for Various Uses and Photographic EnvironmentsFeaturing a dust and splash-proof body and zoom lock mechanism for preventing the lens barrel from extending unexpectedly, the 24-70mm f/2.8 meets a wide range of needs for a variety of photographic environments. 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 for close-up photography. The minimum focusing distance is 18cm at the wide-angle end. Standard zoom is designed for full-frame Sony E-mount mirrorless cameras, however can also be used with APS-C-format models where it will provide a 36-105mm equivalent focal length range.Constant f/2.8 maximum aperture is well-suited for working in available light conditions and also provides greater control over depth of field when using shallow depth of field techniques.Six F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy.Three aspherical elements control spherical aberrations and distortion for increased sharpness and accurate rendering.Both Super Multi-Layer and Nano Porous Coatings have been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.Integrated stepping motor realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance.At the wide-angle end of the zoom range, a minimum focusing distance of 7.1 is possible with a maximum magnification of 1:2.9 to suit working with close-up subjects. At the telephoto end, the minimum focusing distance is 1.25' with a maximum magnification of 1:4.5.Integrated AF-L button can be programmed to adjust various shooting settings and the lens also features a dedicated AF/MF switch and a zoom lock switch to prevent the barrel from accidentally extended.Rounded 11-blade diaphragm contributes to a pleasing bokeh quality.Brass bayonet affords improved mounting accuracy and rigidity and rubber sealing is incorporated in the mount's design to render it dust- and splash-resistant. PRODUCT HIGHLIGHTSFocal length: 24-70mmAperture range: f/2.8-22E-mount lensFor full-frame mirrorless camerasDesigned to minimize flare and ghosting11-blade circular aperture diaphragmZoom lock switch / Lens hood with a lockHigh-precision, rugged brass bayonet mountMount with dust- and splash-proof structureCompatible with the Lens Aberration CorrectionLens Type: Wide Angle to Telephoto Zoom LensSpecial Features: Aspherical, Dustproof/SplashproofSigma 24-70mm F/2.8 DG DN Art SpecsFocal Length24 to 70mmMaximum Aperturef/2.8Minimum Aperturef/22Lens MountSony EFormat CompatibilityFull-FrameAngle of View84.1° to 34.3°Maximum Magnification0.34xMinimum Focus Distance7.09 / 18 cmOptical Design19 Elements in 15 GroupsDiaphragm Blades11, RoundedFocus TypeAutofocusImage StabilizationNoFilter Size82 mm (Front)Dimensions (ø x L)3.46 x 4.84 / 87.8 x 122.9 mmWeight1.84 lb / 835 g
