Samyang AF 35-150mm f/2-2.8 FE vs Sigma 50mm F1.4 DG DN Art
The bottom line
The Samyang AF 35-150mm f/2-2.8 FE is a zoom (35-150mm) and the Sigma 50mm F1.4 DG DN Art is a 50mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter (f/1.4 vs f/2) and lighter to carry. Choose flexibility or a fast single focal length.
Choose the Samyang AF 35-150mm f/2-2.8 FE if…
- ✓You need more reach — it goes to 150mm vs 50mm for distant subjects, wildlife and sport.
- ✓You shoot wide — it starts at 35mm vs 50mm for landscapes, interiors and architecture.
- ✓You want one-lens flexibility — a 35-150mm zoom covers what the fixed 50mm can't reframe.
Choose the Sigma 50mm F1.4 DG DN Art if…
- ✓You want more light and background blur — f/1.4 is faster than f/2, better for low light and subject separation.
