Canon RF 35mm f/1.8 Macro IS STM vs Laowa 180mm f/4.5 1.5X Ultra Macro APO (Canon RF)

The bottom line

These cover different focal lengths — the Canon RF 35mm f/1.8 Macro IS STM is 35mm, the Laowa 180mm f/4.5 1.5X Ultra Macro APO (Canon RF) is 180mm — so they're not really substitutes. Pick by the field of view you actually need: the Canon RF 35mm f/1.8 Macro IS STM for short-telephoto / portrait, the Laowa 180mm f/4.5 1.5X Ultra Macro APO (Canon RF) for telephoto.

Choose the Canon RF 35mm f/1.8 Macro IS STM if…

  • You want more light and background blur — f/1.8 is faster than f/4.5, better for low light and subject separation.
  • You shoot wide — it starts at 35mm vs 180mm for landscapes, interiors and architecture.
  • You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
  • You value portability — at 305g (10.8 oz) it's lighter than the 500g (1.10 lb) alternative for travel and all-day carry.

Choose the Laowa 180mm f/4.5 1.5X Ultra Macro APO (Canon RF) if…

  • You need more reach — it goes to 180mm vs 35mm for distant subjects, wildlife and sport.
  • You shoot close-ups — 1.5x magnification gets you true macro the other can't.
