Frequently asked questions
Why choose it over a 24-70mm?
It is smaller and lighter than most 24-70mm f/2.8 zooms, with the trade-off of starting at 28mm instead of 24mm.
Does the Sigma 28-70mm F2.8 DG DN Contemporary have stabilization?
No. It relies on in-body stabilization where the camera has it.
Is the Sigma 28-70mm F2.8 DG DN Contemporary 021 good for video?
It is usable for video with in-body stabilization on the camera, since the lens has no stabilization of its own.
