www.canonrumors.comHere is Canon Rumor's article:Canon Germany addresses recent Viltrox RF mount lens demands, and it’s a case of patent infrigement
By Canon Rumors | September 6, 2022 | Canon Lens News
Last week a bunch of reports hit the web about Viltrox being told to stop producing lenses for the RF mount by Canon. In an exclusive report, German magazine Photografix has received word from Canon Germany about the issue.
It looks like it affects autofocus lenses being made for the RF mount and patent infringement. What the exactly Viltrox was infringing on is unknown. Rokinon continues to sell AF lenses for the RF mount.
From Canon Germany (Google 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 what does this mean for the likes of SIGMA and Tamron producing RF mount lesnes? We don’t think this clears much up at all. Until we hear from the “big two” third-party brands or more from Canon themselves, we’re all left wondering.

Canon has no obligation to allow anyone else to produce RF lenses that utilize their patented technology. They could sell the right to use these patents if they want. If they maintain their current stance, it remains to be seen whether this might hurt the sales of their cameras and lenses. I doubt it, but you never know.

Nikon allows third party to make their lenses. I don't see anybody jumps ship from Canon to Nikon because of this. I don't think Canon will lose any sales.

I don't think they will either.
Sony has articulating screen.... only have to kneel on ground, not lay on belly, to get a low angle for shooting mushrooms (which I do a lot).... and to shoot from "above" the crowd as well.

Lenses and cameras are two different products. Just because a company makes a top of the line camera doesn't mean that another company can not make a top of the line lens for that camera as long as they have the specs for that camera. In many cases, Tamron and Sigma lenses either exceed those of the camera makers or the differences are microscopic except to pixel peepers. Tamron lenses tend to be stripped down in features and slightly in their build quality, but their prices are striped down as well but not the picture quality. If you are a travel photographer like me, weight and size are important factors. Tamron lenses often excel in that area.
I would agree with you if you said, buy the best quality lenses you can afford if you buy a top of the line camera. My advice would be to be buy the best lens you can afford for any level camera. Even an entry level camera can take amazing pictures with a top of the line lens. Conversely, a top of the line camera with a poor quality lens will take terrible pictures no matter how good the camera is.

It is partly because of Canon's market arrogance towards customers why I left Canon after using their pro gear for over 42 years. So they lost this longtime pro and others I know. But they are so big they dont really care in those corporate offices. lol
This story has been trending across the world and many folks on smaller budgets are weighing in saying they will find other brand options instead of having to choose between buying cheaper quality kit RF glass, or being forced to buy expensive RF lenses to get good RF glass.
People want options and still want quality lenses at reasonable prices to fit their tight budgets. Other fullframe mirrorless makers like Nikon with its Z-mount, Sony with its E-mount, and Panasonic, Sigma and Leica with their shared L-mount get it. Canon seems clueless here.
Cheers and best to you.
Is Canon going after all the 3rd party lens manufacturers who make Canon compatible lenses, or just one?
I have a feeling, without evidence, that there is more to this story than what has been released.

There are still some early produced third party RF lenses left at dealers, but dont expect any new ones . Canon can claim infringement but unless and until they win such a case in courts around the world (an expensive and time consuming thing to do), those remaining third party RF lenses can be legally sold.
But it sends the message and you wont now see Sigma, Tamron and others making any new RF lenses that wont get any firmware support or coding from Canon going forward.
Canon's business model and corporate philosophy is their own, right or wrong. Yes it will cost them some potential R camera buyers , but Canon is so large they wont feel it in those corporate boardrooms, LOL.
Cheers and best to you.

Wrong. Companies own patents on the technology in their equipment. To make lenses using OEM patented technology is against the law unless permission is given or unless a licensing fee is paid. If caught, the best the violator can hope for is a cease and desist order. The worst would be a costly lawsuit. I would be surprised if Nikon isn't getting some licensing fees from third parties like Tamron and Sigma. If not, then they just don't care. Canon takes a different stance on this.

Gerald, given your impressive resume, which you have reminded us of many, many times, why are 95% of the 115 threads you have initiated either touting Sony or bashing Canon? I would think you would have more helpful information with your experience to contribute than these 2 subjects, so here is my question: are you compensated in any way by Sony? If so, now I understand the tenor of your posts, and if not, why not share more of your technical/composition experience rather than focus on Sony marketing?
I am not a huge fans of focus by wire and sold my 24-105 RF because of it just not working right for manual focus. So I actually have yet to buy any other RF lenses, so far just using my old EF, but I was hoping for a sigma art RF mount that does not use the same focus by wire. And yes 95% of the time I am using manual focus.

We shall see.
They can always change direction.

If you are really into manual focus should check out the Zeiss lenses. I am not sure but I think they make some manual focus only lens with large well damped focusing ring,
I guess they don't make them for the RF mount yet.
