The Canon CF-R20EP is a specialized battery grip for the EOS R5 Mark II that includes an ethernet connections and a multispeed fan to keep the camera cool in challenging video production situations and extend recording times.
The 2.5G ethernet port allows for high-speed tethering, letting you quickly transfer large amounts of both photo and video data via the stable wired connections.
The design of the grip accommodates two LP-E6P batteries to effectively double battery life while providing a more stable hold when shooting in a vertical orientation. The grip also features the same weather-resistant construction as the EOS R5 Mark II itself.
