Sigma 35mm F1.4 DG DN Art vs Sony E 10-18mm f/4 OSS

The bottom line

These cover different focal lengths — the Sigma 35mm F1.4 DG DN Art is 35mm, the Sony E 10-18mm f/4 OSS is 10-18mm — 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 10-18mm f/4 OSS for wide-angle.

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, better for low light and subject separation.
  • You need more reach — it goes to 35mm vs 18mm for distant subjects, wildlife and sport.
  • You prefer a fast, compact single focal length — a 35mm prime over a zoom.
  • You like close-focus work — 0.19x magnification vs 0.1x.

Choose the Sony E 10-18mm f/4 OSS if…

  • You shoot wide — it starts at 10mm vs 35mm for landscapes, interiors and architecture.
  • You want one-lens flexibility — a 10-18mm 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 value portability — at 225g (7.9 oz) it's lighter than the 645g (1.42 lb) alternative for travel and all-day carry.
