Key Features
  • E-Mount Lens/Full-Frame Format
  • Aperture Range: f/2.8 to f/22
  • Two FLD Elements, Two SLD Elements
  • Three Aspherical Elements
The 28-70mm f/2.8 DG DN Contemporary Lens for Sony E-Mount from Sigma is a versatile wide-angle to portrait-length zoom characterized by its f/2.8 constant maximum aperture. The design suits working in available lighting conditions while affording increased control over depth of field. More lightweight and compact than similar 24-70mm lenses, it's optical design incorporates two FLD and two SLD low-dispersion elements plus three aspherical elements that reduce a variety of aberrations to achieve high sharpness, enhanced clarity, and improved color accuracy. It 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, an ideal combination for filmmakers looking for a high-performance, lightweight, and easy-to-handle camera system that works well with a gimbal or other accessories.

How much image quality degradation of this compared to Sigma 24-70 2.8, if any?
Asked by: Zhenpeng
This is not something that can be easily quantified. The Sigma 24-70mm f/2.8 DG DN Art Lens is the better lens optically. And it has better build quality. It also gives a wider field of view. The Sigma 28-70mm f/2.8 DG DN Contemporary Lens offers the benefit of being lighter and more compact, while still being a very good lens.

Should I buy this for Video or the old Sigma 24-70 f/2.8 ?
Asked by: Mohammed
This is lighter in weight versus the Sigma 24-70mm f/2.8, but not as wide. The right choice would depend on how wide you need the lens to be.

This or the Tamron ( for video )

This or the Tamron ( for video )
Asked by: Mohammed
Both this and the Tamron 28-75mm f/2.8 for Sony E mount are great options. However, video shooters should take note that this and the big brother to this lens (Sigma 24-70mm f/2.8) offer slightly smoother AF focus pulling when shooting video. The Sony G Master 24-70mm f/2.8 is smoother still. If there's an advantage to the Tamron 28-75mm f/2.8 for Sony E mount it would be that it produces more flare, something that may appeal to cinematographers who appreciate that effect. (Of course, such flares can also be added in post production using professional software, if desired.)

Is this lens parfocal and does it have linear focus throw?
Asked by: Glen
While Sigma makes no claims about the 28-70 f/2.8 DG DN being parfocal, we tested it in the store and the results we quite good; we were able to maintain parfocality throughout the range although we can't claim it to be a conclusive result. As far as its focusing is concerned, this lenses uses a fly-by-wire system rather than a linear/mechanical helicoid focusing system.
