Canon RF 70-200mm f/2.8 L IS USM Z vs Canon RF-S 55-210mm f/5-7.1 IS STM
The bottom line
Similar coverage, different speed: the Canon RF 70-200mm f/2.8 L IS USM Z opens to f/2.8 versus the Canon RF-S 55-210mm f/5-7.1 IS STM's f/5 — more light and shallower background blur. The Canon RF-S 55-210mm f/5-7.1 IS STM gives that up to stay lighter (270g (9.5 oz)) and cheaper ($329). It comes down to how much you value that extra brightness.
Choose the Canon RF 70-200mm f/2.8 L IS USM Z if…
- ✓You want more light and background blur — f/2.8 is faster than f/5, better for low light and subject separation.
