Sigma 35mm F1.4 DG DN Art vs Sony E 70-350mm f/4.5-6.3 G OSS
The bottom line
These cover different focal lengths — the Sigma 35mm F1.4 DG DN Art is 35mm, the Sony E 70-350mm f/4.5-6.3 G OSS is 70-350mm — so they're not really substitutes. Pick by the field of view you actually need: the Sigma 35mm F1.4 DG DN Art for short-telephoto / portrait, the Sony E 70-350mm f/4.5-6.3 G OSS for super-telephoto.
Choose the Sigma 35mm F1.4 DG DN Art if…
- ✓You want more light and background blur — f/1.4 is faster than f/4.5, better for low light and subject separation.
- ✓You shoot wide — it starts at 35mm vs 70mm for landscapes, interiors and architecture.
- ✓You prefer a fast, compact single focal length — a 35mm prime over a zoom.
Choose the Sony E 70-350mm f/4.5-6.3 G OSS if…
- ✓You need more reach — it goes to 350mm vs 35mm for distant subjects, wildlife and sport.
- ✓You want one-lens flexibility — a 70-350mm zoom covers what the fixed 35mm can't reframe.
- ✓You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
- ✓You like close-focus work — 0.32x magnification vs 0.19x.
