Sigma 16-28mm f/2.8 DG DN Contemporary vs Viltrox AF 75mm f/1.2 Pro FE
The bottom line
These cover different focal lengths — the Sigma 16-28mm f/2.8 DG DN Contemporary is 16-28mm, the Viltrox AF 75mm f/1.2 Pro FE is 75mm — so they're not really substitutes. Pick by the field of view you actually need: the Sigma 16-28mm f/2.8 DG DN Contemporary for wide-angle, the Viltrox AF 75mm f/1.2 Pro FE for short-telephoto / portrait.
Choose the Sigma 16-28mm f/2.8 DG DN Contemporary if…
- ✓You shoot wide — it starts at 16mm vs 75mm for landscapes, interiors and architecture.
- ✓You want one-lens flexibility — a 16-28mm zoom covers what the fixed 75mm can't reframe.
- ✓You value portability — at 405g (14.3 oz) it's lighter than the 665g (1.47 lb) alternative for travel and all-day carry.
- ✓You like close-focus work — 0.19x magnification vs 0.12x.
Choose the Viltrox AF 75mm f/1.2 Pro FE if…
- ✓You want more light and background blur — f/1.2 is faster than f/2.8, better for low light and subject separation.
- ✓You need more reach — it goes to 75mm vs 28mm for distant subjects, wildlife and sport.
- ✓You prefer a fast, compact single focal length — a 75mm prime over a zoom.
