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 is does the focus breathing compare to the 24-70?
This 28-70mm definitely breathes more than the Sigma 24-70mm DG DN. I put both lenses at 28mm and with the 28-70mm lens it's much more noticeable.

Is the focus ring compatible with follow focus? Or is an adapter needed?
The Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Sony E uses a fly-by-wire system rather than a linear/mechanical helicoid focusing system, so you would probably want an adapter.

How much image quality degradation of this compared to Sigma 24-70 2.8, if any?
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 ?
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.
