Sigma 28-70mm f/2.8 DG DN Lens for Sony

Smart & Nimble. The New Standard Mirrorless Zoom.

The Sigma 28-70mm f/2.8 DG DN Lens for Sony redefines the standard zoom for mirrorless cameras by combining outstanding optical performance, an F2.8 constant aperture, and a lightweight and compact body. The design of the 28-70mm F2.8 DG DN | Contemporary is based on the existing 24-70mm F2.8 DG DN | Art, but with a focal range starting at 28mm, making the lens body significantly smaller and lighter while maintaining superb optical performance. It is the smallest and lightest lens in its class. Remaining true to the Contemporary line’s core concept of maintaining an optimal balance between optical performance and lens size, this new optic delivers professional quality results in a body small enough to take on a casual outing.

Design Based On SIGMA’s Art Line, With The Same Uncompromising Optical Performance.

The optical design of the Sigma 28-70mm f/2.8 DG DN Lens for Sony is based on the 24-70mm F2.8 DG DN | Art, which is renowned for its outstanding optical performance throughout its zoom range. True to the Contemporary line’s core concept, the 28-70mm F2.8 DG DN | Contemporary was developed to offer the right balance of performance and portability, and as such, this large-aperture standard zoom delivers outstanding image quality that rivals Art line lenses in a body light enough for day-to-day use. Building on state-of-the-art technology, the Sigma 28-70mm f/2.8 DG DN Lens for Sony has an advanced optical design that includes three aspherical, two FLD, and two SLD elements.

A Lightweight & Compact Body ― Ideal For Day-To-Day Use.

Being slightly less wide-angle than the Sigma 28-70mm f/2.8 DG DN Lens for Sony has allowed a significant reduction in the size of the 28-70mm F2.8 DG DN | Contemporary lens body. In order to fit with the design concept of the Contemporary line, which balances performance with portability, the new lens features a simpler dust- and splash-proof structure and smaller switches. This makes it the smallest and lightest lens in its class*. The new lens features just one lightweight focusing element, which keeps the AF unit small. This, along with a quiet and fast stepping motor, makes for responsive and near-silent autofocus performance.

Superb Build Quality With Exceptional Attention To Detail That Provides An Exceptional User Experience.

With priority given to optimal portability, the body of the Sigma 28-70mm f/2.8 DG DN Lens for Sony consists primarily of lightweight parts. While conventional wisdom states that it is more difficult to ensure processing accuracy for plastic parts than metal parts, there has been no compromise whatsoever on build quality for the 28-70mm F2.8 DG DN | Contemporary.
