New Sigma 24-70mm F2.8 DG DN for for L-Mount & E-Mount cameras

The second newly-designed Sigma “Art zoom” dedicated to mirrorless cameras 

 

Best-in-class optical performance

The Sigma  F2.8  Art zoom lens series has been developed primarily to achieve superior optical performance. Extra-low dispersion glass materials, six sheets of “F” low dispersion (FLD) glass and two sheets of special low dispersion (SLD) glass were used, thus taking advantage of an optical design dedicated for mirrorless lenses. Inspired by 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. The lens tailors resolution and achieves uniformity and superior optical performance from the center to the periphery and throughout the zoom range. In addition to super multi-layer coating, a nano porous coating is employed. This lens is designed so as to be less affected by strong incident lightsuch as flare. The mirrorless camera-dedicated design contributes to reduction in the lens size and weight

 

Ensuring compatibility with the latest full-framemirrorless camera bodies

The Sigma 24–70mm F2.8 DG DN ensures compatibility with various types of the latest full-frame mirrorless camera bodies, tailored for L-Mount, and Sony E-Mount. The AFL button has various functions that can be assigned from a camera body, which enhance the operability. Employing a stepping motor and the latest algorithm the Sigma 24–70mm F2.8 DG DN establishes a good balance between acceleration and quietness of the AF drive. This enables stress-free focusing. This lens is also compatible with the eye-detection AF used more frequently in mirrorless cameras, which is capable of high-precision focusing. 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. The maximum magnifications are 1:2.9 at the wide-angle end, and 1:4.5 at the telephoto end.

Finally,  the lens adapts to various uses and usage environments through employment of the dust and splash-proof structure, and the zoom lock mechanism which prevent the lens barrel from extending unexpectedly. An AF/MF switch used for the many conventional Sigma 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.
