The Canon R3 is not waterproof but features professional-grade weather and dust resistance equivalent to the EOS-1D series, making it safe for use in heavy rain or dusty environments.
The Canon R3 can shoot up to 30 fps using the electronic shutter with full AF/AE tracking, and up to 12 fps with the mechanical shutter.
The R3 features significantly improved thermal management over the R5, allowing for over 60 minutes of 4K 60p recording in most standard ambient temperatures.
It uses the high-capacity LP-E19 rechargeable Li-ion battery, which is also compatible with the EOS-1D X series.
