Canon has always delivered great bang for the buck lenses on top of the fabulous L lenses that we enjoy, so it's no surprise that we see a new patent application dealing with the lower end of the spectrum.

When I first read the patent application (2024-072459), I *assumed* that it was Canon looking at future models of the Canon RF 15-30mm f/4.5-6.3 IS STM and the Canon RF 24-50mm F4.5-6.3 IS STM.

There is a “window” on the back of the Canon EOS R1 that seemed to stump us nerds who obsess over the smallest details, but it may actually be a cool detail.



On August 31, 2023, Canon Inc. announced that they had completed a pilot project that focused on authenticating photographs using cryptography. It was a partnership between Thomson Reuters, Canon Inc. Canon Europe and Starling Lab, which is a research lab based at Stanford University and USC.

You can see a full example of the technology at Reuters: Preserving trust in photojournalism through authentication technology. As pointed out by @Klexisnake, who lead me down this rabbit hole. You can check the metadata of the images and you will see the camera identified as the Canon EOS R3. The press release does mention a “prototype Canon camera”, so I think it's likely that the camera identifier was changed for proof of concept, as the EOS R3 was a commercially available product at the time.

Though I will note, the files sizes are 6000×4000. Or I could be completely wrong and it is in fact, a rear selfie camera.

Original Press Release

Canon & Reuters team up in developing cryptographic methods to authenticate photographs​

TOKYO, August 31, 2023—Thomson Reuters, a global content and technology company, Canon Inc., and Canon Europe Ltd., a world-leading provider of imaging and information technology solutions, and Starling Lab, an academic research lab based at Stanford and USC innovating with the latest cryptographic methods and decentralized web protocols, announced today the completion of a pilot program demonstrating how news organizations could certify the authenticity of an image and ease concerns about content's legitimacy.

In collaboration with Canon, global news organization Reuters proved its ability to embed trust into a photograph from its source by preserving a picture’s data provenance chain of integrity – the image’s metadata – from the point of capture to publication. Reuters also successfully integrated Starling Lab’s authentication framework into its picture desk workflow. One of the first practical news-gathering applications of the technology, this pilot comes at a time when consumers are increasingly worried about their ability to distinguish between real and fake news on the internet, and recent advancements in generative AI technologies which are making it easier for anyone to create visuals to deceive or misinform viewers.

“Trust in news is critical. However, recent technological advancements in image generation and manipulation are causing more people to question what is real, and what is not. Reuters continues to explore new technologies to guarantee that the content we deliver to the world be factual and trusted,” said Rickey Rogers, Global Editor, Reuters Pictures. “Our collaboration with Canon demonstrates the potential for new technology in image verification to increase consumers’ confidence that what they see is genuine. We look forward to sharing the encouraging findings from the project with our customers and applying them to protect our photojournalism. Our goal is to remain one of the most trusted global news sources.”

The pilot project saw Reuters photojournalist Violeta Santos Moura capture pictures using a prototype Canon camera that digitally assigns each photograph and its corresponding time, date and location with a unique identifier (hash value) and then cryptographically signs them to establish a root of trust for their authenticity. The photos are then registered into a public blockchain and updated after each modification by the Reuters pictures desk. This process continues until the photo is distributed with its metadata, edit history and blockchain registration embedded in the photograph using the new C2PA standard. To verify the picture’s authenticity, news customers can compare its unique identifier (hash value) on the public ledger.

“Many photojournalists rely on Canon technologies. We understand the role that images play in society and recognise the importance of preserving image authenticity”, said Richard Shepherd, Product Marketing and Marketing Strategy Senior Manager, Canon Europe Ltd. “Working as part of the Content Authenticity Initiative (CAI), Canon wants to take meaningful measures to protect image outputs that serve the news community worldwide.”

Since this announcement 8.5 years ago, Canon has quietly forgotten about the camera they were at one time developing for us. This was the 120MP DSLR with a stunning resolution of around 13,400 x 8,900. That’s a lot of MegaPickles™. Canon was confident at the time that they would have the sensor technology, and the

I've been watching the price of the RF 100-500 over the last few months and noticed a sudden price drop at most of the big UK retailers yesterday. These don't seem to be Canon rebate drops, but a separate voucher at checkout - in the case of the RF 100-500, £500 which gets it much closer to the grey importers. This seems to be across a number of different lenses, so perhaps a Canon attempt at shifting some stock off the shelves in time for replacement lenses or just a way to stem the grey import market?

No, that’s not a typo. Kodak has just dethroned Canon has the #1 manufacturer of digital cameras because of their wildly successul compact digital cameras, capturing 22.5% of the entire market. This data was supplied by BCN which means it is for the Japan market only, but there is something odd going on with the

First, I'm sorry. I haven't read all comments to all posts here on CR. So this might have been mentioned before. But someone on dpreview saw a possible hint of what to come in the little EOS R1 teaser video.

First look at the R3 teaser video. In hindsight it clearly hints the Eye Control AF feature.


Then look at the red pattern "flashed" over the EOS R1 title in the R1 teaser video:


"Quad Pixel" sensor design?

Besides for better autofocus, if true, could such a design also be used for the rumoured dual-gain support?
One pair of sub-pixels with "high" gain, and the other pair of sub-pixels with "low" gain?

I don't know much about dual-gain sensor designs, but I assume the advantage would be higher dynamic range.

Okay, I bet that got your attention. I have long talked about the need for smaller travel cameras that we got spoiled with, with the EOS-M system. The ability to take a small, but capable kit, anywhere, on any airline is important to some, especially in some areas of the world where it’s getting increasingly

What's your thoughts regarding the material used for the RF L lenses? I don't like it. It feels cheap and not like the EF L lenses. For example the RF 100-500 is all plastic except the tripod mount. My EF 100-400 feels lika a tank when compered. All metal and very solid build.

After talking about the EU and why that didn’t seem to be causing any of the delays, the conversation in the forums, after discussing golf rangefinders, made a note that there seemed to be a supply shortage across all manufacturers. Someone mentioned Thom Hogan talking about it, and then something clicked in my lizard brain

Some active conversations are happening that cameras are being delayed because of EU regulations that went into effect this year.
