Introduction
The R5C camera is a remarkable tool for video professionals, offering the ability to shoot RAW video in 8K atup to 60 frames per second. However, this feature comes with certain limitations. Due to the small battery, the camera can’t get enough power to record full 8K 60p and simultaneously provide power to the lens. This results in loss of AF, image stabilisation and aperture control of most modern lenses.
However, there is a solution to this problem: Providing the camera with an external power source. In this article, I will explore a creative solution that not only unlocks the R5C’s 8K capabilities but also maintains its lightweight and versatile design.
Current solutions
To shoot in 8K 60p RAW with full lens control, the camera requires an external power source connected to its USB-C port. For studio or stationary setups, a simple charger from a device like a MacBook will suffice. However, the R5C is designed for adventure and mobility, making bulkier setups involving cages and V-Mount batteries impractical. These setups compromise the camera’s hybrid capabilities and add unnecessary weight.
Instead of resorting to V-Mount batteries, you can opt for regular power banks with a USB-C Power Delivery output of at least 45W. These power banks can provide the necessary power for 8K recording, but a new challenge arises: where to mount the power bank. This is where our innovative DIY solution comes into play.
A DIY Solution for Run-and-Gun shooting
My goal was to create a handheld, easily mountable solution that would still allow me to shoot photos with the EVF without detaching components. After extensive research, I found a power bank with a 60W USB-C power delivery output that perfectly fit beneath the camera without protruding. In addition to that, the power bank has a nice flat shape, which makes it easier to create a mounting solution.
To securely attach the power bank to the camera, I designed a custom cage that held the power bank snugly in place. After several prototypes and creative design ideas, I achieved a working version of the cage. The cage can be attached to the bottom of camera by a 1/4″-20 screw and is hold in place by two locking screws, similar to other camera cages. This way, the battery cage doesn’t rotate or comes loose during a shoot. The cage incorporates a sliding door on the left side. This door securely locks the power bank in place when closed, while it can be opened to release the power bank easily. This design allows me to use the power bank for other devices like my phone or other accessories when needed or replace it during longer shoots. Remarkably, this cage and power bank combo weighs similarly to the BG-R10 battery grip, ensuring that the camera remains lightweight for extended use.
To enhance the setup’s versatility, I added a 1/4″-20 thread underneath the cage for easy tripod mounting. Additionally, I incorporated an industry-standard ARCA-SWISS quick-release mount on the bottom plate, enabling the camera to be effortlessly mounted on various tripods without the need for additional quick release plates.
Having a normal USB-C dangling from the camera wouldn’t be a nice and sleek solution. The cable would get in the way during shoots and also hold a risk to damage either USB-C port and lead to a broken camera or power bank. To overcome this issue, I used a short, rubberized USB-C PD cable and two 90 degrees magnetic USB-C connectors. This way, the cable is the right length, sits snug against the camera and doesn’t dangle around and if it gets ripped out, the magnetic connections save the ports on the camera and power bank.
Conclusion
With this DIY solution, I have successfully overcome the limitations of the R5C camera while preserving its lightweight and versatile nature. Shooting 8K 60p RAW video is now within easy reach for run and gun shooting, and the ability to easily mount the setup on tripods and replace power banks during extended shoots adds to its appeal.
