Product Details / Description:

The SIGMA 28-70mm F2.8 DG DN redefines the standard zoom category by prioritizing portability without compromising on optical excellence. This lens is an ideal choice for travelers who want professional performance and background separation (bokeh) but need a light setup for exploring Japan all day.

About the Product

The lens construction features 16 elements in 12 groups, including two FLD (F Low Dispersion) elements and two SLD (Special Low Dispersion) elements, along with three aspherical lenses. This generous use of special glass thoroughly corrects various aberrations, ensuring sharp, high-contrast images from corner to corner.

The constant F2.8 aperture is perfect for low-light shooting and separating your subject from the background. By optimizing the design specifically for mirrorless cameras, SIGMA has achieved a feather-light mass of just 470g, making it incredibly comfortable for extended handheld shooting or video use. The stepping motor ensures fast, quiet, and reliable autofocus, fully supporting advanced camera features. Furthermore, the close minimum focusing distance of 19cm at 28mm provides a maximum magnification of 1:3.3, offering great versatility for close-up detail shots.

Faqs:

How does this lens compare to traditional 24-70mm F2.8 zooms?

The key difference is size and weight. While the 24-70mm offers a slightly wider start (24mm vs 28mm), this lens is significantly lighter (470g vs 800g+) and smaller. By trading the 4mm at the wide end, SIGMA created a high-quality F2.8 zoom that is genuinely comfortable for all-day use and travel.

Why is the optical design based on the Art line lenses?

SIGMA used the optical performance of its highly-regarded Art line lenses as a benchmark for this Contemporary lens. This means the 28-70mm F2.8 delivers exceptionally high resolution, minimal aberrations, and superb contrast, providing image quality close to that of the professional Art series in a more portable form factor.

How useful is the close minimum focusing distance of 19cm?

A 19cm minimum focusing distance at 28mm is excellent for a zoom lens. It allows you to create dynamic shots where you highlight a small foreground subject (like a bowl of ramen or a small souvenir) while still capturing the background context, a technique known as “wide-angle close-up.”

Does this lens have image stabilization?

No, the lens does not have built-in Optical Stabilization (OS/VC). Like many modern mirrorless lenses, it is designed to leverage the powerful 5-axis In-Body Image Stabilization (IBIS) system found in most Sony E-mount camera bodies, which provides effective shake correction.
