Sony FE 28-70mm f/2 GM vs Sony FE 50mm f/1.4 GM
The bottom line
The Sony FE 28-70mm f/2 GM is a zoom (28-70mm) and the Sony FE 50mm f/1.4 GM 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.
