The Canon EVF-V50 OLED Viewfinder is an add-on accessory for the Canon EOS C500 Mark II 5.9K Full-Frame Camera that attaches to the rear of the camera to add a 1.77 million dot OLED viewfinder for a more traditional monitoring solution.
Will this work on any cameras other than the Canon C500 Mark II?
No this viewfinder is only compatible with the Canon EOS C500 Mark II 5.9K Full-Frame Camera.
No. The EU-V1 and EU-V2 expansion units use the same connection point as the viewfinder and cannot be used at the same time as this viewfinder.
