Laowa 180mm f/4.5 1.5x Ultra Macro APO AF vs Sigma 20-200mm F3.5-6.3 DG Contemporary
The bottom line
The Sigma 20-200mm F3.5-6.3 DG Contemporary is a zoom (20-200mm) and the Laowa 180mm f/4.5 1.5x Ultra Macro APO AF is an 180mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter and lighter to carry. Choose flexibility or a fast single focal length.
