CR3 Files

The R5 was added in last week’s Lightroom Classic 9.4 update, so if you don’t yet have that version, you’ll want to go to the Updates tab in your Creative Cloud desktop app and choose Check Updates from the “…” menu at the right side.

The reason others were confused when you asked about CR3 files instead of R5 files, is because Canon uses the CR3 filename extension for many cameras going back several years. So CR3 files have been supported for a long time, but the CR3 files coming specifically from the sensor of a Canon EOS R5 have been supported only since last week. Nikon and others do the same thing with their filename extensions, one filename extension covers raw files from many models old and new.
