Laowa 90mm f/2.8 2x Ultra Macro APO (Nikon Z) vs Tamron 70-300mm f/4.5-6.3 Di III RXD (Nikon Z)
The bottom line
The Tamron 70-300mm f/4.5-6.3 Di III RXD (Nikon Z) is a zoom (70-300mm) and the Laowa 90mm f/2.8 2x Ultra Macro APO (Nikon Z) is a 90mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter (f/2.8 vs f/4.5) and lighter to carry. Choose flexibility or a fast single focal length.
