The Sigma 24-70mm f/2.8 DG DN Art and the Nikon Z 24-70mm f/2.8 S are both professional-style standard zooms with a constant f/2.8 aperture. The biggest practical difference is mount: the Sigma is made for Sony E and L-mount cameras, and the Nikon is made for Nikon Z. For most buyers the camera system decides the answer before any other feature does.
What each lens is for
These are the core lenses for weddings, events, portraits, reportage, travel and general work. The 24-70mm range moves from a wide environmental view to a short portrait length, and f/2.8 holds up in dim rooms while giving a clear separation from the background.
The Sigma is a third-party lens in the Art line, which the maker positions for image quality. The Nikon is a first-party lens from the S-Line, which the maker describes as its top optical tier for Z-mount lenses.

Native lens or third-party lens
A native lens is designed alongside the camera, so features such as focus modes, in-camera corrections and firmware updates are usually well supported. A third-party lens can offer a different balance of size and value, but it is worth checking which camera features it supports.
Because these two lenses fit different mounts, you are really choosing a camera system as much as a lens. If you already own a body, that decision is made.
How to decide
- Match the lens to your camera mount first.
- If you are choosing a new system, compare the lens lineup you will want over several years, not just one lens.
- Think about video: check how each lens handles focus breathing and zoom ring feel.
- Compare the control rings and switches on each lens to see which suits your workflow.
FAQ
Can I mount the Sigma on a Nikon Z body?
The DG DN Art version is made for E and L mounts, so it does not fit Nikon Z directly. Check with the makers before using any adapter.
Is f/2.8 enough for low light?
It is a common working aperture for events and indoor shooting. Pair it with a shutter speed of roughly 1/125 to 1/250 for people and raise ISO as needed.
The Short Version
Choose the Nikon if you shoot Nikon Z and want the camera maker’s own standard zoom. Choose the Sigma if you shoot Sony E or an L-mount camera and want an Art-line zoom. Confirm details on each maker’s page.
