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.

Best-in-class optical performance
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 center to the periphery throughout the zoom range.

MTF CHART
The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens' performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1).
The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is.
*The MTF chart depicts the result at the wide-open aperture.
*For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.)
*The spatial frequency indicates the variation on the image plane before distortion correction is performed.

Hyper Sonic Motor (HSM)
The Hyper Sonic Motor (HSM) uses ultrasonic waves to drive the autofocus mechanism. It features extremely quiet operation, high torque, and excellent focusing speed.
Exclusive low-dispersion glass
Careful arrangement of exclusive low-dispersion glass elements gives SIGMA lenses superlative image rendition untarnished by residual chromatic aberration.

High compatibility
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 so as to be capable of exerting the best performance under any photographic circumstances, assuming that professional or advanced amateur photographers use it.
Adaptable to various uses and photographic environments
In consideration of shooting under challenging shooting conditions, the dust and splash resistant structure* and water- and oil-repellent coating are adopted. In addition, a variety of functions, such as an AFL 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 provided.
