Sigma 24-70mm f/2.8 DG DN II Art (L-mount) vs Sigma 85mm f/1.4 DG DN Art (L-mount)
The bottom line
These cover different focal lengths — the Sigma 24-70mm f/2.8 DG DN II Art (L-mount) is 24-70mm, the Sigma 85mm f/1.4 DG DN Art (L-mount) is 85mm — so they're not really substitutes. Pick by the field of view you actually need: the Sigma 24-70mm f/2.8 DG DN II Art (L-mount) for standard zoom, the Sigma 85mm f/1.4 DG DN Art (L-mount) for short-telephoto / portrait.
Choose the Sigma 24-70mm f/2.8 DG DN II Art (L-mount) if…
- ✓You shoot wide — it starts at 24mm vs 85mm for landscapes, interiors and architecture.
- ✓You want one-lens flexibility — a 24-70mm zoom covers what the fixed 85mm can't reframe.
- ✓You like close-focus work — 0.32x magnification vs 0.12x.
Choose the Sigma 85mm f/1.4 DG DN Art (L-mount) if…
- ✓You want more light and background blur — f/1.4 is faster than f/2.8, better for low light and subject separation.
- ✓You prefer a fast, compact single focal length — an 85mm prime over a zoom.
