Canon EOS Multi Remote App
Canon EOS Multi Remote is a remote camera control application that enables linked shooting with multiple cameras, setting changes, and automatic FTP transfers. It provides powerful support for professional photography, contributing to improved efficiency and quality on set. It can be downloaded from the company’s website .
Thanks to evolving camera technology, sporting moments can now be captured with unprecedented realism and intensity. However, at large-scale events, the number of photographers is limited, and there are many situations where one person needs to operate multiple cameras. The EOS Multi Remote is an innovative system that can remotely control up to 10 Canon cameras. It allows users to capture decisive moments from multiple angles, providing powerful support to professional photographers active in sports events.

Main Features
- Shoot from multiple angles with a single release: Multiple cameras shoot simultaneously in conjunction with the photographer’s camera. You can use a smartphone or tablet to configure cameras set up in different locations and synchronize them with your own camera.
- Control up to 10 cameras at once: Multiple cameras can be grouped together for shooting control.
- Never miss a decisive moment: Live view lets you capture the decisive moment without missing a beat.
- Intuitive operation: The intuitive shutter button placement allows you to shoot while looking at the subject.
- Freely change shooting settings at your fingertips: You can change shooting settings such as ISO sensitivity, Tv, Av, and WB from your smartphone or tablet, and you can set them one by one or for all cameras at once.
- Shoot, review, and share in real time: You can review images immediately after shooting and use the information to improve your next shoot. Images can be transferred directly from the camera to the server using the app. Images are shared instantly.
