If I were Canon, I would make this guy a generous job offer to integrate a better stock heat spreading solution and optional external cooling into future camera models.
Kudos to the guy for debugging his particular problem, but that doesn’t make a product.
In the video he more specifically describes how it could be possible to use the mounting point's metal base to transmit heat to a mounted cooling attachment.
I haven't even started watching this video and had the same thought of transporting the heat through the bottom.
Whatever made canon made it like this, was on purpose.
Either the concentrated on picture for the most time and realized to late and it would have required rebuilding core parts and not getting it out in time or they will bring out a camera/pro version to this with unlimited 8k recording and with a higher price.
The assumption that a hobby engineer can solve this issue while canon can't, is not realistic.
Based alone on the original firmware approach, i would argue that time or priority was the issue.
So it was never impossible, and it isn't just a Nerf to segment customers into the cinema bracket. It's just an area where they're willing to compromise.
Without IBIS, the αN < 6500s aren't great for many video applications, they're photo cameras which can also take some video. I suspect that Sony just didn't realize the degree to which the YouTube generation would be using their entry-level mirrorless systems for extensive video. Consider that it took them a generation to make flip screens standard, and that they bumped the battery size and ability to record indefinitely on (only) the model which has IBIS: that's a nudge, saying "If you want to record a lot of video, the α6600 is the model you want".
I think that's more evidence that the overheating problem wasn't a deliberate attempt to segment customers into the cinema bracket, but rather something Sony didn't realize would be such a problem, because who is going to want to film 100 minutes on their photo camera? Practically everyone as it turns out.
Yeah, they could have and should have added better heat dissipation: but they can and should make (much) better software as well, and don't, because... it's Sony.
However, the management did overlook it. Now the machine overheats and requires hours of cooling down to shoot continuously for more than 20-25 minutes. Is that an acceptable amount considering any kind of film work?
The market segmentation is totally different for that.
I would still buy it. I have a Canon 80d and 90d and i rarely do any video recording at all. why? Because just a recording ready body doesn't give you good video. You need audio equipment etc. and 8k video is huge like wtf huge.
Probably the same reason laptop manufacturers design their cooling to be barely adequate. It would cost less than a dollar to make it dissipate the maximum TDP at full load (not just "normal" load).
To make it easy, let's ignore ultrathin laptops - even mobile workstations have had the same terrible heat dissipation for over a decade, with very few exceptions.
How do you figure?
> It might not be intentional, but it sure doesn't hurt them.
I just explained why video cameras have different requirements than DSLRs. Besides which, 4K30 or 1080p60 is plenty of unlimited video capability for most consumers. The camera can even do 8K30 and 4K60 for longer than most people take videos.
The laptop thing - using a bigger heatsink, or more copper, or better thermal paste, or multiple heatpipes instead of one (that was actually HP's solution to their overheating ZBooks) would cost pennies and would actually keep the CPU/GPU under throttling limits.
I've repasted and modified enough laptop heatsinks to know it's a very easy thing to do. But the manufacturers don't care. I get it, a dollar saved on one machine is a lot of money overall. I'd rather have it cost $10 more but have a decent heatsink.
Yes, they're working as intended.
SLRs are optimized for handheld, photography use. The body just doesn't have the surface area for proper long-term cooling, and even if it did, it could be difficult to get it to work well while maintaining water resistance and retaining the compact grip.
