So we finally have an 8K mirrorless camera with a headphone socket I may add.

Before you rush out and spend your £4000 there are some serious flaws this camera is going to give you from day one.

For UK customers 8K 25P creates a lot of heat (There is no fan in this camera) and as the heat builds up in the camera you will get short recording times even as low as 15 minutes or less.

No one understands why Canon decided to go down this route as a filmmakers we need equipment we can rely on.

It seems to me Canon wanted to have the first interchangeable mirrorless camera filming in 8K to jump ahead of the competition but with no fan to cool things down have they jumped in too soon.

You have to question why Canon did not look at the Panasonic S1H recording at 4K and ask themselves why Panasonic needed a fan in their camera.


Canon just issued an official statement regarding the Canon EOS R5 and EOS R6 overheating during video recording. The company says they used a magnesium alloy body and “overheat control” for better heat management. Canon didn’t want to include a fan to keep the body compact and weather-sealed.  The EOS R5 can only record up to 20 minutes in 8K and up to 15 minutes in 4K 120fps. After that, the camera needs up to 20 minutes to recover before starting to record again.

HDW…We can safely say the R5 won’t be finding itself on any blockbuster studio set anytime soon with that crippling 20 minute wait between takes.


Having been working in the video business since 1988 I have amassed a great amount of knowledge of both the kit and production values over the last 30 years.

6 thoughts on “Canon R5 “8K at a cost” Price £4200

  1. Philip, with all respect, I think you’re making the mistake of looking at this from a narrow viewpoint. You say “as filmakers” – but is it really intended “for filmakers”?

    I’d argue not. The very form factor screams a camera primarily intended for taking STILL photographs. In many occasions it may be very desirable to have a camera primarily for just that purpose – but with the ability to sometimes record video clips. And that’s what I see here. Why make it more expensive that it needs to be (cooling, headphone socket etc) for a purpose it’s not mainly designed for?

    If you’re a filmaker – buy a video camera. Don’t buy a still camera (with a bit of extra functionality thrown in) and complain it’s not perfect for the job.

    HDW : David I agree so why promote the 8K video mode at all if your market share is for the photographer (PS AS I have stated IT DOES HAVE A HEADPHONE SOCKET).

  2. “No one understands why Canon decided to go down this route” – I think most people know why they did. Protection of the Cinema line of cameras of course.

    HDW : Just as well Panasonic don’t think this way.

  3. Canon just missed the oportunity to make a perfect 4k 50/100fps-10 bit camera. They are well known for their past failures regarding video performances in other cameras of theirs.

  4. 8K video….my take
    This is, IMO, INSANE.
    A ton more work and time to make a microscopic gain in the final result over 6k—which is also a little crazy. The vast number of people don’t even have displays good enough to show 8k or even 6k.
    In the company I worked for our sales people were taught to present our products (I was product designer) in the light of what they called FaB: Features and Benefits.
    The one thing they were told never to do was to ask the customer to weigh the Cost of a given Feature in the light of what the Benefit actually provided.
    I saw people pay lots of money for the added Benefit—but they seldom if even used—-even though they paid a LOT more for the Feature. In some cases they actually removed the Feature after a period of time that provided the costly Benefit, because it got in the way of other things that were lots more useful.
    That’s called Sanity—but coming a bit too late to save you the time and money.
    IM videographically, unschooled, uneducated, but albeit logical and reasoned oriented O, this is a sales gimmick; just one among the tens of thousands of Manufacturer’s FaB scams, and nothing more.
    The moral? Don’t let temporary insanity cause you to plunder your bank account for something that will, metaphorically speaking, sit in the corner and collect dust.
    My 2¢

  5. Quote: “@HDW : …..why promote the 8K video mode at all if your market share is for the photographer”
    I think it’s more a case of “why not?”, if it can be done for little extra cost! 🙂

    And that should be the case, likely be just adding extra functionality (video codec etc) to the main chip, so probably not requiring much (if any) extra hardware. Don’t forget the whole concept of video from a DSLR came from the “liveview” facility. Eventually someone realised that offering the ability to record such was a low cost marketing advantage, and whilst early implementations were awful for moiré, better processing left it fine for video quality.

    But what distinguishes a video camera (nowadays!) from a still camera is less picture quality than usability, connectivity and ergonomics – and that includes such as a fan! That would cost extra, and to someone buying the camera primarily for stills use would be unwanted bulk, weight and expense. Same with a lot of similar features that are important for a “true” video camera, but a disadvantage for a stills camera – pro timecode, XLR and other connectivity, etc etc. Before even thinking about servo lenses etc.

    And I’m afraid I disagree with David above about “Protection of the Cinema line”. I suspect it’s the old story simply of economies of scale – how many such still cameras get sold for every pro video.

    But to answer “why promote the 8K video mode at all”, then apart from the “big numbers sell” theory, then I can think of a number of uses in such as the scientific and technical field where such a feature could be very useful. It comes back to my original point – don’t look at it from a narrow “filmmaking perspective”, being able to record video is applicable to many other purposes than traditional filmmaking.

  6. William Ridenour says “A ton more work and time to make a microscopic gain in the final result over 6k—which is also a little crazy.”
    William – it’s primarily engineered in respect of the chip and processor for top quality still photography. The likelihood is that the video mode – be it 8k or whatever – has cost next to nothing to add. The chip has that resolution for stills – so if the processor can manage it, why not allow it for video?

    It would be adding features such as the fan that WOULD cost extra money – whilst being unnecessary for stills work, and (as Canon say) destroying weatherproofing. Personally, I think Canon have got it right – it’s Panasonic who have fallen between stools. The S1H isn’t a “real” video camera – but compromising it’s dust/water resistance makes it less valuable as a rugged stills camera.
