Smart And Nimble. The New Standard Mirrorless Zoom.
SIGMA sets a new standard in large-aperture mirrorless zoom lenses
The SIGMA 28-70mm F2.8 DG DN | Contemporary lens for L-mount 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.
In addition to prioritizing portability, SIGMA’s optical engineers introduced a new combination of coatings and structural elements that make this standard zoom well-equipped for use in a wide range of shooting environments. Likewise, the latest production and manufacturing techniques were employed to ensure exceptionally high build quality. The 28-70mm F2.8 DG DN | Contemporary introduces another fast, high-performance, large-aperture zoom lens to SIGMA’s mirrorless line-up, offering a more compact alternative to the existing 24-70mm F2.8 DG DN | Art.
Design Based On SIGMA’s Art Line
With The Same Uncompromising Optical Performance
The optical design of the SIGMA 28-70mm F2.8 DG DN | Contemporary for L-mount 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.
A Lightweight And Compact Body
Ideal for Day-to-Day Use
The SIGMA 28-70mm F2.8 DG DN lens for L-Mount features a simpler dust- and splash-resistant structure smaller switches and just one lightweight focusing element, which keeps the AF unit small. This makes it the smallest and lightest lens in its class.
The supreme portability afforded by a camera system that weighs less than 1kg gives photographers a huge amount of freedom and flexibility to achieve their creative vision.
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 F2.8 DG DN | Contemporary 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.
