Thanks to KolariVision, and thanks @Richard CR for sharing this (real) insight

I would never do that myself, but as a technician, I am always fascinated seeing these teardowns.

Getting my R8 converted is an interesting idea, but I should first use up the rolls of IR capable film in my fridge using my TLR before sending in my digital camera

I now know how it can be weather sealed while having vent holes. Wonder if any moisture is trapped in there, or if it will quickly dry out. Might have a little garden in there if it’s not vented and dried well enough

probably not much difference than making sure your lenses don't start growing mold, etc. just have a few bags of silica that your camera rests on will take care of anything.

These big packs are great for gear - and they also keep my damned new Canadian passport from warping into a "U"

Don't think of it as holes going into the body, consider them weirdly shaped attachment points, they don't puncture the outer shell. The tripod socket is also a hole into the body and people don't get as upset with that as with these vent channels.

If they’re closed plastic dents, how do air travel through? I doubt much air flows through the tripod mount?

Thanks Richard, such teardowns are what I liked most about LensRentals.
I miss them, especially the lens teardowns...

If I blow cold air through my fist, it will cool my skin and through that, my hand. But the air doesn't go into my body, nor do my insides leak out through my fist. The R5II is similar, the vent channels won't let air into the electronics, the big metal plate shown in the article will dissipate the heat from the electronics to the vent channels.

This is basically the same principle of glueing a heatsink to the outside of the camera and attaching the LCD to that. The fins will look like holes since they are sandwiched between the camera and the LCD, but their are still very much external.

I realize that both English and Dutch doesn't have a clear way to distinguish between 'inside' as in 'bread inside a lunchbox' and 'inside' as in 'inside a tunnel', making this hard to express in writing. If they do have words or concepts like that, I'll be happy to be enlightened!

Be reassured, your "little garden" will be fully organic. Enjoy your free veggies!

Excellent, thank you so much for explaining

So the USB-C port is still part of the motherboard. Tetherers beware!

EDIT: Umm, can I tether using HDMI-mini to the HDMI port on my laptop?

Inside as an preposition (key inside a lock) vs. Interior as an adjective (interior house walls)?

I totally forgot that the day I got my precious I was curious about the heat and checked the camera with my FLIR ONE Edge Pro.
If anyone is interested and curious... I made these shots immediately after a test drive of shooting my cats in their natural home habitat

)))

No videos. Nothing fancy. If you want something specific let me know... will try to test it.

Enjoy.

wow nice!

I'm actually a little surprised about the heat on the sensor itself actually.

all you have to do is shine a light down the vents to see that there is no exposure to the internal components. all you see is metal plating.

it's a similar concept to the Canon V10 camera. It's not exactly the temperature that causes it to overheat. It's the inability for the surrounding environment to whisk away the heat. I had the camera in an enclosed room with no moving air that was around 70F. It overheated fairly quickly when I set it to the skin smoothening filter. But that the camera outside with even higher temperature but with some air blowing (even when it's warm air) is enough to keep the camera from overheating.

yes, canon has spent a considerable amount of effort devising ways of shunting off that heat.

it's even more complicated because of the moving IBIS platform.

I have a IR converted 400D that I use for the occasional IR BnW shot. However, a IR converted R8 would be a nice full frame upgrade.
