Precautions On Multi Shot Noise Reduction - Canon EOS R5 Advanced User's Manual

Caution

Precautions on Multi Shot Noise Reduction

If there is significant misalignment in the image due to camera shake, the noise
reduction effect may become smaller.
Be careful about camera shake in handheld shots. Using a tripod is recommended.
If you shoot a moving subject, the moving subject may leave afterimages.
Auto image alignment may not function properly with repetitive patterns (lattice,
stripes, etc.) or flat, single-tone images.
If the subject's brightness changes as the four consecutive shots are taken,
irregular exposure in the image may result.
After shooting, it may take some time to record an image to the card after
performing noise reduction and merging the images. "BUSY" is displayed as
images are processed, and shooting is not possible until processing is finished.
