Canon EOS R5 & R6 Overheating Issues

Recommended Posts

I have to say that I'm somewhat gobsmacked at the amount of defensive manoeuvres being fielded towards the Canon R5 and R6 overheating issue. I just don't see it as a minor issue that will only affect a few. And those claiming these are just stills cameras I think are somewhat deluding themselves. Canon is advertising these as both stills and video cameras. Canon wants these to be considered as such.

The thing that has struck me more than anything else is a simple, though indirect, comparison with the BMPCC4K and 6K. Even to this day, I hear and read about people complaining about the battery life of these two cameras, with the most recent example stating that it's 'horrendous'. I haven't noticed anyone coming to their defence (other than myself), yet through my own tests using a genuine Canon LP-E6N battery shows that I can get 52 min of continuous 4KDCI recording, at any outside/inside temperature (I've done so outside when when it's been 43.7C in the shade and the camera did not falter). The battery life is not 'horrendous', given that the battery is only 14Wh. It may not be sufficiently powerful for some shooters, but it's not horrendous.

So, how is this relevant? Well, if say 50 min of recording time is not sufficient for the BMPCC4K, then how is 20 min (or less) recording time for the R5/R6 suddenly sufficient (forgetting the additional cooling times)? Then there's the other take. I can easily attach an external battery (NP-F, V-lock, power bank etc) and get unlimited shooting time by simply swapping batteries as needed and letting the internal battery act as an UPS. You can't effectively remove heat build up from the R5/R6 to improve the operational time.

So if Canon had advertised the camera as mainly a stills camera with crappy video qualities, then I don't think anyone would have made such a fuss, but they didn't. They made video capabilities a major feature. So the arguments as to why overheating with the R5/R6 is not a problem is truly gobsmacking.

The other thing I forgot to mention is that one of the other 'complaints' about the BMPCC4K/6K have been that they require accessories such as cages and external monitors. It looks like external monitors (and likely cages) will become the 'in thing' now that the R5/R6 are here, as it appears the only way to record longer sessions is by using an external monitor recorder. Karma is a bitch. 😄

 Are people forgetting about this?

Tilta had a cage for the a6 series with a fan already. Not trying to defend canon. That thing is a mess but it's not the first to get a cooling solution from tilta 😄

 

Sony managed to address their over heating problems with a FW up date ,and I guess some legal arse covering where it says opting for the 'High" temperature freehold option in the menu could damage your camera.. but basically they had set the cut off limit way too low and no one has had a problem with the high settings ..  and thew A camera,s just dont over heat anymore .. not sure if Canon have that leeway with the 8K sensor ..

If there's a possibility for a firmware update for the Canon, I'm sure Cannon is working every person to the bone, day and night, to find a solution. But I guess I'm experiencing a bit of schadenfreude with all of this.

For nearly two years now I've listened to people constantly bagging the BMPCC4K (and 6K) for any reason they can find seemingly in order to deter people from getting one. It's the 'horrendous' battery life, no flippy screen, no EVF, no IBIS, no ability to take proper photos, bad design, needs accessories before it can be used and whatever else. None of which is an issue whatsoever.

So now it's been revealed that the 'King' has no clothes and his minions are desperately out in force declaring that he is in fact magnificently attired. Excuse me if I enjoy popcorn for a change. 😄

yeah have to say a part of me is glad that 8k is a total mess..  I think the whole K thing is marketing bollocks ..  6k down sample to 4K seems to be the Goldilocks level.. for 99% of any productions.. at the most..

Sure make a specialist 8k camera  for effects .. like there is for high speed ..  , but in a mirrorless stills camera video mode  ..????   14 mins record time and 20 mins to cool down .. yes good thinking Canon management  ,Im sure that was worth 1,000 meetings .. and the A7s111 coming out .. I'd be selling my canon shares .. presumably the engineers were against it but over ridden by their fearless leaders in suits ..

It's a stills camera. From the beginning they said the 8K and other video codecs are compromised, which should be apparent considering no other manufacturer is putting out 8K raw in a form factor anywhere near the R5. Figuring out the right gear is part of everyone's job. Would you be happier if Canon had not mentioned the 8K raw? I'm going to buy one if only for the stills capability, even though I'm mostly shooting video these days. There is plenty of information available to make a professional's decision about whether to buy it without the suggestion that Canon is trying to defraud the film making community.

Canon heavily touted its 8K video capabilities, with the clear intent of implying that it was above all other hybrid cameras. No one is saying that Canon is or was trying to defraud anyone, the camera can clearly take 8K video, even if it's for a few seconds. That few seconds seems to be borne out given some statements that the overheating begins with stills shooting and thus affects the video ability. Time will tell how the camera fares in the real world.

    • Thanks for the kind words guys 👍  Joeri, Colony we shot on a Sigma 18-35mm T/2 and the Red 50-150mm T/3. And The Good Wild Man was shot on the Zeiss CP.2s. 
    • I have a Selens 120cm carbon fibre slider that I motorised and a 30cm Zeapon Micro 2 slider that's not motorised (though a motor is available).  I also have an Edelkrone 30cm knock-off that I bought ages ago. My slider (which I'll explain) is for when I go bush and want movement in scenes where there is none. The 120cm was my first slider, but proved to be way too long for taking bush and the Edelkrone knock-off was a pile of crap. The Zeapon, on the other hand, is one of the most impressive sliders that I can imagine and provides the smoothest of operations imaginable, even without a motor. It's my bush slider. I would never even consider an Edelkrone given the prices they charge and I'm not sure they are all that good given some YouTube videos I've seen. But that's just me. I don't understand what colour has to do with sliders. The start of this video was shot with the Zeapon and the Selens slider. Can you pick which was which? https://www.youtube.com/watch?v=ggGRSe5svrI
    • Love the shorts too! Which lenses are used on the first 2? my pmw-f3 should arrive in 1 week -:) still need to decide on my lenses, I was thinking of Slr magic apo microprimes. love to hear about the grading: over or underexposing. grtz, Joeri
    • 1) MYT Works Large 4’ slider.  Self-contained, smooth, large payload capacity, well built, easy(ish) to travel(4’ and below fit in gun cases). 2) Multi-cam interviews, occasionally b-roll, but small gimbals have been replacing sliders for the same style of b-roll over the last few years for speed(no set-up). Videographer, while a technically correct word, is a bad word and no one likes to be referred to as one*.  It’s connotation and association is largely with low-end and wedding shooters from the 80’s/90’s era.  I’m not a DP, but do not call me a videographer.  Call me a shooter, photographer, cameraman, photog, cam-op, camera monkey, asshole, ‘hey you’, or pretty much anything else, except videographer.  Or late for dinner.   *Kind of like ‘police’ and ‘cop’.  In some circles, cop is considered a derogatory term for police or police officer.
    • I can't comment on Edelkrone products, but I use a Cinevate Horizen slider: because it's the most compact slider that takes the full weight of my camera, and has a lower centre of gravity than another option (MYT Works) and is significantly cheaper than the other options (Matthews, Grip Factory Munich, and Ronford Baker). Question 2: all sorts! Locations, studios, interior, exterior. As for question 3: whatever the client asks for!
