Canon RF-S 14-30mm f/4-6.3 IS STM PZ vs Canon RF7-14mm F2.8-3.5 L Fisheye STM
The bottom line
Similar coverage, different speed: the Canon RF7-14mm F2.8-3.5 L Fisheye STM opens to f/2.8 versus the Canon RF-S 14-30mm f/4-6.3 IS STM PZ's f/4 — more light and shallower background blur. The Canon RF-S 14-30mm f/4-6.3 IS STM PZ gives that up to stay lighter (210g (7.4 oz)) and cheaper ($399). It comes down to how much you value that extra brightness.
Choose the Canon RF-S 14-30mm f/4-6.3 IS STM PZ if…
- ✓You need more reach — it goes to 30mm vs 14mm for distant subjects, wildlife and sport.
- ✓You're on a budget — $399 vs $1,899 leaves more for other gear.
- ✓You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
- ✓You value portability — at 210g (7.4 oz) it's lighter than the 476g (1.05 lb) alternative for travel and all-day carry.
Choose the Canon RF7-14mm F2.8-3.5 L Fisheye STM if…
- ✓You want more light and background blur — f/2.8 is faster than f/4, better for low light and subject separation.
- ✓You shoot wide — it starts at 7mm vs 14mm for landscapes, interiors and architecture.
- ✓You work outdoors — it's weather-sealed against dust and moisture; the other isn't.
