Laowa 17mm f/4 Zero-D Tilt-Shift vs Sigma 28-105mm F2.8 DG DN Art
The bottom line
These cover different focal lengths — the Laowa 17mm f/4 Zero-D Tilt-Shift is 17mm, the Sigma 28-105mm F2.8 DG DN Art is 28-105mm — so they're not really substitutes. Pick by the field of view you actually need: the Laowa 17mm f/4 Zero-D Tilt-Shift for wide-angle, the Sigma 28-105mm F2.8 DG DN Art for standard zoom.
Choose the Laowa 17mm f/4 Zero-D Tilt-Shift if…
- ✓You shoot wide — it starts at 17mm vs 28mm for landscapes, interiors and architecture.
- ✓You prefer a fast, compact single focal length — a 17mm prime over a zoom.
- ✓You value portability — at 810g (1.79 lb) it's lighter than the 1055g (2.33 lb) alternative for travel and all-day carry.
Choose the Sigma 28-105mm F2.8 DG DN Art if…
- ✓You want more light and background blur — f/2.8 is faster than f/4, better for low light and subject separation.
- ✓You need more reach — it goes to 105mm vs 17mm for distant subjects, wildlife and sport.
- ✓You want one-lens flexibility — a 28-105mm zoom covers what the fixed 17mm can't reframe.
- ✓You work outdoors — it's weather-sealed against dust and moisture; the other isn't.
Where they differ
