We have about 7 hours to go at the time of writing this for the official announcement of the Canon EOS R6 Mark III and RF 45mm f/1.2 STM. This has been an exiting launch period and you can feel why the 6 series is Canon's best selling full-frame cameras

What the hell is wrong with me?

For the first time ever doing this site, I actually have a moral dilemma as to whether release them, or just let Canon do it. People at Canon work hard, from the marketing and sales teams, to the people that actually design and build these things. They have lawyers too, but I don't like them. :)

I have decided to release the first page, it does answer some questions that we were unable to confirm, and most of them are for photographers, and honestly, photographers feel left out sometimes when new cameras launch, there is so much emphasis on video. I am a photographer, period.

I know this is a rumors site, but the fun is trying to piece of all together over weeks and months. Once the announcement happens, that part of the fun is gone… until the next one.

So here it is.

Canon EOS R6 Mark III: Some Official Specifications

I dunno

I hope that everyone that preorders this camera can get it soon after it starts shipping on November 25, 2025. It would be great if we these cameras in-stock before Christmas, that will mean Canon really did a great job with the launch.

That's that, video people can wait or someone else can leak that stuff. :)

  1. Looks to be a nice camera. I will not be purchasing since I already have the R5 Mk2. If I did not have the R5 Mk2 I would seriously consider this camera for travel photography (landscapes, street) where having a stacked sensor is not a necessity.

  2. I haven't read all the comments in the other R6III thread, so maybe it has already mentioned...

    But I'm 99% sure the photo from Alan Photo is just a mockup - an edited photo of the R6II. I think it is also confirmed by the new image from Canon France. Look at the microphone holes. It looks like they are on top. When looking at photo from Alan Photo they sit at the front just as they do on R6II.

  3. I have the version ii and think, at least for me as a wildlife shooter and filmer, the only real gain would be the 4k120 fps (if the R6 mk iii has this feature ofcourse). For the money I have to add for the version iii I'll keep my version ii and wait for the R7MKii next year.

  4. I am debating with myself whether to buy the R6ii which will be heavily discounted starting Nov. 7th - I'd be upgrading from the EOS R. I'd mainly do it for the AF system, but I'd lose crop ability. Since I do mainly wildlife and birds (in Southern Africa), I am also considering just sticking with the R and instead getting the RF 200-800 and upgrade to the R6iii on Black Friday 2026...

    The R6ii is wayyy better than the R. Depends how urgently you need it though. On the photo side, the R6iii does not look significantly better to me than the II with the exception of pixel count. The II is a very good camera. Maybe you could also wait for an R7ii and get a 100-500?

    Yes, I could also do that. And it's driving me crazy, haha. Right now I have the R and the Sigma 150-600 - so upgrades are needed on both ends. The question is in which order. I do like the EOS R, it's just the weak AF that is additionally weakened by the lens and the adapter...

    If I were you I would always first go for a better lens. It is these that give you the best results. the R is maybe not the best option nowadays but if you compare it with camera's of the era before the mirrorless it is definately good! R7mkII with RF 200-800 (or the 100-500 plus converter albeit more expensive) and you have a top notch combo! And don't worry about the "low light performance" .. you are in South Africa my friend 😉

  8. does any one know what the weight of the R6mk3 is versus the R7?
    R6iii is likely to be 60-70 grams heavier with battery and cards. Will that be a dealbreaker for you?

    I unterstand completely. In 2022, I went on a safari in Kenya. I was facing the same dilemma as you are right now. In the end, I decided to upgrade my 100-400mm lens with the RF 100-500mm and the 1.4 extender and I kept the EOS R. For most part I did fine and got great pics, but when I spotted a fast running leopard I only managed to get two sharp pics and basically 50 unusable ones. In 2022, prices for the R6 and R5 were still (also covid related) very high, so I opted the other route. The R7 didn't ship in time... my initial idea was to pair the R7 and the R. Oh well, still did good/ great pics.

    For you, depending on your budget, I´d consider the following scenarios:
    - get a R7 + 200-800mm and go with a two cameras. The R is great for landscapes and slowy moving animals like elephants and giraffes.
    - get a used R6 + 200-800mm and take a two camera set-up as mentioned above. The R6 AF is not on par with mkii, but still lightyears better for wildlife than the R.
    - sell the R, get the R6mkii
    - sell the R, get the R6mkii, sell the Sigma and get your dream lens.

    The price for the R6iii will be sky high for about 12-18 months. First cash backs/ discounts usually run at 250 $. Until it hits the price point of 2.200 $/€ it will be a while.

    In Germany, the differences between a used EOS R and R6 on eBay are about ≈ 400 €, if you're lucky even just 300 €. Maybe you could sell the R, get the R6, be for happy for now and get the R6iii for Black Friday 2026/ 2027 and end up with a great two camera set-up. That´d be my way to go. If I ever go on a Safari again, I´d definitely bring a two camera setup.

    Thank you for your insights. But I will keep the R for landscapes, astro and as a backup. And I know the frustration of trying to shoot moving animals with it. I'll upgrade the lens first and see what 2026 will bring to the table...

  11. There are two things I am excited about: low light capability and the bump in auto focus. I'm strictly a hobbyist and I'm currently shooting a 6Dm2. Perhaps the r6m2 would be a big enough jump in both of those areas. Particularly the low light.

    Thing is, I mostly shoot my kids sports and they play soccer/futsal and basketball. I'm really excited to try the action priority settings (in concert with the low light boost for futsal and basketball).

    Only did a cursory search, but I haven't been able to find a ton of real world reviews about those soccer/basketball action modes. The reviews I did see say they're pretty good, but not earth shattering.

    In any case, super excited to check it out.
