Some rumor are surprisingly smart when it comes to the perfect timing. The long running and now-and-then surfacing rumor about a Canon EOS R with APS-C sensor seems to belong to this category.
Just a few days after someone suggested Canon might kill the EOS M lineup, someone else suggests that Canon will release an EOS R model with crop sensor.
We always had a hard time to buy this rumor, independently of the source. The Canon EOS M lineup is well established, has a fond user base, and is a best seller with the EOS M50. So why the hell should Canon kill the EOS M lineup? And why should they come up with an EOS R camera with APS-C sensor? Wouldn’t even further fragment their offering?
However, the EOS R with with a crop sensor gets shifted fro year to year. It’s now rumored for 2021 but I bet in 8 or 10 months it will be rumored for 2022. I migth be wrong but I call the EOS-R-with-APS-C nothing but a fantasy (or bs, your mileage may vary). If someone has a compelling argument for such a camera, I’m listening.
Now, this camera is packed with innovative features and has some rather advanced video modes, as for instance a 4K@120 slow motion mode. Since you are a serious manufacturer you clearly and transparently document the recording times one can get with the advanced video modes. You know, a lot of heat gets produced when computing 4K and 8K videos. Since you do not want to break the camera you made, you put some necessary recording time limits for the advanced video modes to safeguard the circuits and electronics. And so far all is good.
But then, an army of trolls that breath and live technology and cinematography decides to test these video recording times, and they find out you have been totally honest and clear when stating them. This makes them very, very, very angry and they start to hate you because your camera can’t break the laws of physics and because it still is better than anything they have seen so far. And now you’re at the center of a s**t storm and you can’t help but wonder who the hell needs to make a slow motion video that lasts more than 20 minutes. Hell, you don’t know. Neither do the trolls.
It’s a soap opera, isn’t it? All those people fighting for clicks.
We will not feature the most exalted people here. You won’t have a hard time to find them if you really want. What follows is a bunch of links and videos of people who deal with and discuss the EOS R5 overheating drama, each in his own way and with his own claims.
Someone who went for a truly hackerish way to see what it is about the EOS R5 is Math Class on Baidu. He already tore down the EOS R5 and found some interesting things. Kudos!
Then there is the Scotch tape hack, already posted but featured here again.
Tony & Chelsea Northrup have their own ideas and opinions about the EOS R5 overheating drama.
I do not know what to think about Theoria Apophasis and his theories about a silent EOS R5 recall by Canon. Sounds rather unrealistic to me, not to call it else.
Armando Ferreira is set to tell you the TRUTH about OVERHEATING on the EOS R5.
And finally, here is another hack, this time by Matt Granger.
Still want more? Here is a YouTube listing for the EOS R5 overheating drama. Strangely enough, the almost exploding and finger-burning EOS R5 is the best selling camera in Japan.
Another Canon patent application for an RF mount lens, that’s a lens for the Canon EOS R full frame mirrorless system.
Hi Lows Note spotted Canon patent application 2020-118816A. The patent application describes the optical formulas for an RF 200-800mm f/6-8.5 lens.
Focal length: 199.97 399.99 784.76 mm
F number: 6.00 6.80 8.50
Half angle of view: 6.17 3.10 1.58
Image height: 21.64 21.64 21.64 mm
Lens length: 285.44 355.65 385.65 mm
Back focus: 22.57 43.72 83.86 mm
Interesting: the patent application also discusses optical formulas for a RF 100-500mm f/4.5-7.1 IS USM lens. We guess it might well refer to to just announced RF 100-500mm f/4.5-7.1L IS.
Focal length:101.99 199.92 489.99 mm
F number: 4.60 5.20 7.20
Half angle of view: 11.98 6.18 2.53
Image height: 21.64 21.64 21.64 mm
Lens length: 222.94 272.65 312.20 mm
Back focus: 19.88 36.44 69.71 mm
More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production are these:
