Canon updates its list of products affected by supply chain issues

If by 'this lens' you mean the 5.2mm dual fisheye, then most likely no, it will not be compatible with the R3.

any particular reason? It’s the same image circle on the same sized sensor, right? Just seems weird not to have it functional on a much more functional (at least in terms of specs) VR video camera (the R3). I really want this lens, but I can’t justify it, if it’s locked into the R5.
