Canon RF 600mm f/11 IS STM vs Voigtlander NOKTON 40mm f/1.2 Aspherical (Canon RF)
The bottom line
These cover different focal lengths — the Canon RF 600mm f/11 IS STM is 600mm, the Voigtlander NOKTON 40mm f/1.2 Aspherical (Canon RF) is 40mm — so they're not really substitutes. Pick by the field of view you actually need: the Canon RF 600mm f/11 IS STM for super-telephoto, the Voigtlander NOKTON 40mm f/1.2 Aspherical (Canon RF) for short-telephoto / portrait.
Choose the Canon RF 600mm f/11 IS STM if…
- ✓You need more reach — it goes to 600mm vs 40mm for distant subjects, wildlife and sport.
- ✓You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
Choose the Voigtlander NOKTON 40mm f/1.2 Aspherical (Canon RF) if…
- ✓You want more light and background blur — f/1.2 is faster than f/11, better for low light and subject separation.
- ✓You shoot wide — it starts at 40mm vs 600mm for landscapes, interiors and architecture.
- ✓You value portability — at 287g (10.1 oz) it's lighter than the 930g (2.05 lb) alternative for travel and all-day carry.
