Canon EOS R5 Mark II Mirrorless Camera Body

The stacked design allows for faster readout speeds, enabling high-speed continuous shooting and advanced video capabilities like 8K RAW recording, while the back-illuminated structure improves light gathering for better low-light performance.

Yes, you can use Canon EF lenses by utilizing a Canon EF-EOS R mount adapter. The type of adapter may offer additional control options, but a basic adapter will allow for full functionality.

The camera supports 8K 60fps Raw video recording, 4K 60fps SRAW, and 4K 120fps 10-bit recording.

For optimal performance, especially for high-resolution video and burst shooting, CFexpress Type B cards are highly recommended. SD UHS-II cards are also supported for general use.

Eye Control AF uses subtle eye movements detected by the viewfinder to shift the autofocus point. When enabled, looking at a specific part of the frame directs the AF point to that area.

The DIGIC Accelerator works alongside the DIGIC X processor to significantly enhance AI-based functions, leading to improved subject recognition, tracking performance, and overall camera responsiveness for both stills and video.

Check that the correct AF area mode is selected. Ensure the subject is within the frame and well-lit. Clean the lens contacts and the camera's AF sensor contacts.

Check that the memory card has sufficient free space and is rated for the required write speeds. Ensure the camera is not overheating; allow it to cool if necessary. Verify recording time limits are not exceeded.

Perform a power cycle by turning the camera off, removing and reinserting the battery, then turning it back on. If the issue persists, consult the manual for a hard reset procedure.
