A new Canon rumor surfaced. Canon might be set to announced four L-grade prime lenses for the RF mount within the next 12 months.
These are the rumored lenses:
Moreover, the Canon RF 135mm f/1.8L USM might also get announced soon, maybe it is the first one to get announced.
Stay tuned.

After the story about Viltrox having told by Canon not to make RF mount lenses broke, some speculations about the reasons surfaced.
What might be the reasons? Canon Germany released a statement to Photographix Magazine (emphasis mine):
“SHENZHEN JUEYING TECHNOLOGY CO.LTD, manufactures auto focus lenses for Canon RF mount under the brand name “Viltrox”. Canon believes that these products infringe their patent and design rights and has therefore requested the company to stop all activities infringing on Canon’s intellectual property rights.”
So, all about copyright and patents, duh? That doesn’t seem to satisfy those who inquire more, and are keen to speculations. It is suggested, Canon does not have any “plans to give permission to third party manufacturers to utilize their RF mount patents as they pertain to electronics and autofocus anytime in the near future.” The reasons for that are listed as follows:
* Canon doesn’t feel the RF lineup is anywhere near maturity, and they want the lineup filled out with their own lenses first. Canon still has lots of work to do in both the non-L and L lineups.
* Canon believes the “more affordable” options are already covered by the hundred and whatever million EF lenses out there that work extremely well on the RF mount with Canon’s line of adapters.
* Canon isn’t done with tweaks and improvements to the RF mount.
This might well be the case. Never the less, it seems a bit of a far stretch to us and we wonder how much of this is just educated guess. What do you think?

Does Canon not want Viltrox to manufacture lenses for the RF mount? Seems so.
It started with a user in the DPReview forum who posted a chat with Viltrox. Apparently, as you can read below, Viltrox has been “told by Canon to stop selling all RF mount products“.
Now, there is a follow up to this. So far Canon did not release any official statement. But now Canon Germany answered to German Photographix Magazine, and Canon said (machine translated):
“SHENZHEN JUEYING TECHNOLOGY CO.LTD, manufactures auto focus lenses for Canon RF mount under the brand name “Viltrox”. Canon believes that these products infringe their patent and design rights and has therefore requested the company to stop all activities infringing on Canon’s intellectual property rights.”
So, it’s about patents and intellectual property. Anyways, not cool at all dear Canon. Change your mind asap, please.
A new Canon patent for RF mount lenses: 20mm f/1.8, 28mm f/1.8 and 24mm f/1.8.
Canon patent application 2022122047 (Japan) discusses optical formulas for three RF mount lenses with backlight control. From the patent literature:
An object of the present invention is to provide an optical system that is less affected by unnecessary light and has high optical performance.
Description of the Related Art
There is a demand for further improvement in performance and miniaturization of photographing optical systems. [0005]When trying to improve the performance of an optical system, the number of lenses constituting the optical system increases. On the other hand, if an attempt is made to reduce the size of the optical system by shortening its overall length, the distance between the lenses constituting the optical system and the distance between the optical system and the imaging surface will be shortened. As a result, unnecessary light (ghost) caused by reflection of light on each lens surface easily reaches the imaging surface.
SUMMARY OF THE INVENTIONAccordingly, it is an object of the present invention to provide an optical system that is less affected by unnecessary light and has high optical performance.

A new rumor, about the Canon RF 300mm f/2.8L IS lens. Is it coming? The EF version is discontinued.
A rather confident rumor suggests that Canon might be close to announce the Canon RF 300mm f/2.8L IS lens. Says the source of the rumor:
[…] Canon has prototypes out in the wild and that the lens is a ground-up redesign of the focal length.[…] weight has been reduced by almost 40% and the length by as much as 30% over it’s EF predecessor, though they didn’t have the exact dimensions and weight to give us.
The lens is rumored to get announced at the beginning of 2023.
Stay tuned.

I do not like this kind of rumors. Rumors born out of the fact that it is very likely that Canon will release a given lens (or gear). It’s the case with the Canon RF 35mm f/1.2L lens for the EOS R system.
There is no doubt this lens will come to EOS R system, sooner or later. So why not start a rumor? Says the source of the rumor:
[it had been] reported that it would be announced in 2021, and then in 2022, and now we are told that the lens has been pushed back to 2023. We’re not exactly sure why the lens has been pushed back, but I think that we can assume as to why, and we’re tired of typing the reasons!
I guess the reasons are the usual supply chain issues, mother of all issues. So, after having been rumors for 2021 (with a certain confidence), now the Canon RF 35mm f/1.2L is a 2023 affair. See here all Canon RF 35mm f/1.2L rumors listed since their beginning. There is also a patent referring to the lens.
Stay tuned.
