A Canon RF 18-45mm lens has been on the Canon Rumors RF lens roadmap for quite some time, and I have always thought it was a weird choice for full-frame cameras, I have thought in the past that the lens would work well for both full-frame and APS-C image sensors.
A new patent from Canon shows an RF 18-45mm f/4.5-6.3 for what appears to be an APS-C sensor. I say RF because I don’t believe there will be any new EF-M lenses, though this patent may just be to protect design ideas and won’t come to market.
The image height of 12.44mm-13.66mm lines up with an APS-C application.
