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.

Choose the Laowa 90mm f/2.8 2x Ultra Macro APO (Nikon Z) if…

  • You want more light and background blur — f/2.8 is faster than f/4.5, better for low light and subject separation.
  • You shoot close-ups — 2x magnification gets you true macro the other can't.
  • You prefer a fast, compact single focal length — a 90mm prime over a zoom.
  • You value portability — at 375g (13.2 oz) it's lighter than the 545g (1.20 lb) alternative for travel and all-day carry.

Choose the Tamron 70-300mm f/4.5-6.3 Di III RXD (Nikon Z) if…

  • You need more reach — it goes to 300mm vs 90mm for distant subjects, wildlife and sport.
  • You want one-lens flexibility — a 70-300mm zoom covers what the fixed 90mm can't reframe.
