Did you know that your R5 can now take 400MP photos? Well, if you install the latest firmware (version 1.8.1) on your camera, it can. Which I did, so mine does.
The new update adds 'IBIS High resolution shot' mode to the Canon EOS R5. This makes use of the in-body image stabilization system to amplify the sensor's native 45MP resolution to an enormous 400MP – a trick that's been used in other cameras for years, but is a first for a Canon body.
