It's interesting to see your thoughtful post, Harry. But I don't think that you can rely on any camera to be put on a tripod in order to disapate enough heat to make it a needed element to cool an otherwise too-warm camera. The reason is that it will often not be put on a tripod and then you are back to square 1. Canon could have routed their inner R5 heat sink metal strips to the tripod socket, but to my recollection the lensrentals teardown indicated that they did not bother to do so.
I previously suggested that Canon consider a small portion of one or more camera sides to contain a small hollow channel or channels through a stainless metal heat pipe to allow air to rise from the bottom to the top of the camera, dissipating heat naturally without need of a fan. It would be designed to allow moisture, or rain, to enter into it which would further cool the camera and there would be no way that moisture/water could enter any other region of the camera as is it totally enclosed within the heat pipe(s). The hole(s) on bottom & top could be quite small and almost unnoticeable.
Canon could even take this one step further and design the outer side walls to be a stainless metal design with continuous columns of small hollow channels allowing air to rise from small holes on the bottom to small holes in the top of the metal sides, almost unnoticeable. Of course the metal sides could still have a normal rubberized skin attached for normal ergonomic in-hand feel.
What do you think of this? If it has merit, then I'd be interested in your thoughts of how a possible design could be created and submitted to Canon. I don't have the ability to do this, but you probably do if you're interested.
If the R1 has a quad-pixel FF sensor with 8K video, that will be a lot to pack into a single 40+ MP sensor (probably ~45 MP with IBIS). I could see that being a possibility.
As a 'cropped' MF sensor and having 100mp the pixel pitch is, unfortunately, not much different to your asp and FF digital format now, being about 3.6um. A 50mp FF sensor has a pixel pitch of 4.1um. Personally I'd rather have 50mp (1.7 x FF) DMF sensor.There's inherent differences in the sensor size and the images it can generate as well as pixel density. Furthermore, the GFX line is really "cropped" medium format. It's only marginally bigger than a full frame 35mm sensor, and doesn't come close to reaching the sensor size that's equivalent to the old Hasselblad 6x6 or Mamiya 6x7 format.
Today, Canon is fitting 32.5 M pixels with 2 photosites each into an APS-C sized area with the 90D and M6 II sensor. That's 2*32.5 = 65 M photosites on an APS-C sized area, and could be scaled up to 1.6^2*65 M = 166.4 M photosites on a FF sensor. With 4 photosites per pixel, that would result in 41.6 MP. So purely in terms of manufacturing the photosites, it seems Canon has the technology to pull off QPAF already.8K requires 33MP, which I think is plausible. Quad pixel AF requires 4 photo sites per pixel, which requires >130 million photo sites. I don't see that happening. Even two photo sites, alternating between vertically and horizontally, seems too much to me.
R5 is $2500 less than sony a1 not $1500.AND please ALSO NOTE Fuji's introduction of the GFX-100s camera for $5999 USD which offers a full 100 megapixel MF sensor!
Introduction and Q&A with a photographer who actually shot with the camera. Fujifilm has just announced its fourth medium format camera, the GFX100S, a smaller, yet still powerful sibling of the flagship GFX100 and the GFX50S. Even though it houses the same 102MP, back-illuminated medium format...mediumformat.com
Comparing the Sony A1 to the Canon R5 and the Fuji GFX-100s, I feel soooooo sorry for Sony that showed an UNDERWHELMING CAMERA when compared to the $3899 proper DCI-8K Hollywood Cinema/Netflix/Amazon/Apple-play production friendly 8129 x 4320 pixel Canon R5 camera and the 100 megapixel Medium Format Fuji GFX-100 for $5999 US.
The ONLY THING that gets me going for the $6498 USD Sony A1 is the 30 fps Burst Rate at the full 3:2 still photo size image frame and the 120 fps 4K video!
For the Best-Bang-For-The-Buck race, the winner is the Canon R5 for being $1500 cheaper than the Sony A1 and having full DCI 8K Hollywood Cinema production friendly video capture.
For the megapixel and light sensitivity race, the Fuji GFX 100s with 100 megapixels for $5999 WINS HANDS DOWN!
For compactness and toughness, the it's-a-steal for $349 GoPro Hero-8 Black with 60 fps 4K and 240 fps 1080p video is clipped to my helmet!
The Sony has 30 fps full-size still photos as 3:2 and 120 fps 4K video -- That's it!
Is that worth the $1500 Price Premium over the Canon R5?
If you're a TRUE Sony fan, then YES it's MUCH better camera than the Sony A92 but that $6499 price just kills me!
I someone gave be $6500 today, which camera would I buy of the above?
The answer is the Fuji GFX-100s cuz I want a truly LIGHT SENSITIVE MF sensor AND I WANT 100 megapixels!
I'll admit, I would be slightly disappointed if the R1 is higher than 40 megapixels. I already have 45 megapixels on my R5, so I would far prefer 60-120 FPS still photographs at 30 megapixels than 30 FPS stills at 50 megapixels. That said, if the market is truly changing so drastically in this way(24 megapixels has not caused any issue on the 1D or A9), I guess I would appreciate both of my cameras being similar in resolution like the 5D3 and 1DX2 were.
A camera can be weather sealed without being thermally sealed.Exciting! I am glad this actually gives them time to work out all the details which would result of a more fine-tuned product in the end. Hope R1 will solve some of R5's pains in that it will have a bigger body, but given the weathering sealing, one might not expect magic when it comes to heat dissipation.
how theyre making the sony a1 without flip screen is stupid.

8K on a FF sensor requires around 8192 x 5461 min. sensor, or 44.7MP. With IBIS I could see this approaching 50MP. With a quad pixel technology per pixel it will take so much detail that I don't really think it will happen, but it might.8K requires 33MP, which I think is plausible. Quad pixel AF requires 4 photo sites per pixel, which requires >130 million photo sites. I don't see that happening. Even two photo sites, alternating between vertically and horizontally, seems too much to me.
OK - very funny!---
WOW !!!! You just described our cooling system patent documents on our 16K camera !!!!!!!
Where did you get these ideas! We thought along the same path! We'll be releasing the docs next week and you will see a BIG SIMILARITY in our cooling system to what YOU just described!
Great Minds Think Alike!
Canon could potentially obsolete the A1 in one R5 firmware update.Exciting!
