This video shows a man using most of his body strength, towing his cement-filled truck with a Canon DSLR as part of the tow line. I thought this was rather enlightening about durability. How many companies possibly build their cameras, or part of, this tough?

Sorry, not buying it. someone pushing truck from behind. Real test person would show no trickery being used.

You probably don't do physical work of this sort I'm guessing.

I've been doing arborist, landscape and university work for 40 years, using ropes many times. I can tell from the man's body, feet, and lean how much pressure is being applied, and have no need to see the truck.

Video is a waste of time. Sorry I watched.

It's not really a good test of durability. The joints of pressure are shared and essentially has the force in a line. You could do this with anything really. Things that should crumble.

Do the test with the joints of pressure around the lens collar and one side of the body and see what happens.

Very best,

Why?

If the point he's looking at is the tripod mount noted in his video title, why should he bother at all with the lens collar? Seems that would an entirely different experiment

What you wrote seems more related to the question at the end of my OP, although it further grows the question.

Basic physics. He's pulling on the tripod mount at it's absolute strongest angle to resist force. Had he done that test with the camera on a tripod cemented in the ground, standing up right (as it would normally) and the camera mounted on the tripod and pulled at the tripod mount then, this wouldn't be a thread or a video. The test is pointless for even the purpose here.

Pick any angle that is normal for the camera/tripod/etc. Picking the strongest angle that is totally unnatural for the joints that are being stressed here, clearly going for the best representation that misrepresents what the purpose is.

Very best,

Actually, whether he did what you suggested or just what he showed, I think it's remarkable the camera held together even with force from a single angle.If I did that to my cell phone or cordless phone in the house, it would shatter to pieces instantly.

The pull shown in that video would rip the arms off our dining room chair, tear the lid off my printer, snap our ceiling fan and bust most light fixtures in our house.

What's so impressive? Can you tell me the degree of incline/decline of the surface the truck is on? How about the rolling resistance of the truck? You're choosing to be impressed by something without knowing even basic details about what you are actually observing. There's nothing remarkable here, just simple physics.

When you can tell me exactly how many ft-lbs of energy are being exerted on the tripod mount, then we can start discussing whether or not this is impressive. Until then it's just cute parlor tricks.

Yep all that durability makes for some mighty fine photographers. Just get you one of those and you are on your way ha ha ha.

Actors can fake and make anything look real.

Thinking it's "fake" is just as bad as thinking it's evidence of some sort of incredible camera durability.

Vehicles are literally designed to roll with as little resistance as possible, since anything else would, you know, sort of defeat the whole purpose. Getting one moving isn't exactly some great feat.

There's probably a half dozen things in the video that answer and clarify. But I'm not going to note what's telling yet.

For others ... feel free to look for the clues.

Different ... although I watch Dig Rev's youtube channel sometimes. A British-like accent sets it apart too.
