Patent: Canon RF 70-240mm f/4 IS and RF 70-300mm f/4-5.6 IS

Would the L designation necessarily be included in a patent application?
Not per se. But in the Canon lineup, there is only one constant aperture zoom lens that’s not an L lens, the EF-S 17-55/2.8 IS (unless I’ve missed one or more). All FF constant aperture zoom lenses are L. To me, that suggests an RF 70-240/4 IS will have a red ring.

I agree... I think that for the RF trinity tele you might get your choice of f2.8, or f4 with slightly longer reach. Kind of like 24-70 f2.8 vs 24-105 f4.

I guess it means different things to different people. What’s affordable to us may be very expensive to others.
however, Neuro is right. reading the OP: We also expect some more affordable offerings ....

So not an affordable lens in absolute terms but relatively affordable in comparison to available RF lenses. makes sense.
