1. High-Speed SDXC UHS-II Memory Cards
The Canon EOS R6 Mark III is equipped with dual high-speed SDXC UHS-II memory card slots. Because the camera can capture 10-bit 4:2:2 4K Fine video in C-Log3 alongside high-speed RAW continuous bursts, using cards with sustained write speeds is critical to prevent buffer slowdowns or recording stops.
Cards like the SanDisk Extreme PRO SDXC UHS-II (V90) or ProGrade Digital V90 offer sustained write speeds exceeding 250 MB/s, guaranteeing smooth data throughput during rapid burst sequences. Utilizing dual V90 cards allows you to configure real-time redundancy by mirroring video and stills simultaneously across both card slots.

3. Power Solutions: LP-E6P Batteries & BG-R20 Battery Grip
Continuous video recording, high-bright EVF displays, and continuous autofocus tracking increase power consumption during long event days. The R6 Mark III utilizes Canon’s high-output **LP-E6P rechargeable battery**, which delivers the current required for advanced video and burst features.
For all-day shoots, attaching the official **Canon BG-R20 Battery Grip** provides significant advantages. The grip holds two LP-E6P batteries, effectively doubling your shooting time, while providing duplicate vertical shutter buttons, main dials, and AF point selectors for comfortable portrait-orientation shooting.
