Samyang AF 24-70mm f/2.8 FE vs Sigma 50mm F1.4 DG DN Art
The bottom line
The Samyang AF 24-70mm f/2.8 FE is a zoom (24-70mm) 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/2.8) and lighter to carry. Choose flexibility or a fast single focal length.
Choose the Samyang AF 24-70mm f/2.8 FE if…
