> Am I the only one with strong objections to using Zoom as a verb? People will use it or not use it regardless of objections...

That is neither relevant or entirely true. I was not yelling "hey everyone, stop using this word!", I was asking whether anyone else sees the same problems in its use as I do. And even if I were, telling people why you object to something in hopes they agree and maybe do something about it is literally how discourse works.

I webex with people. I have teams meetings. I zoom with people. I have hangouts. I'm meeting on discord. I have sob conferences (that's what we call old lync/skype for business calls).

I don't care what verb you use as long as the link is correct.

Please take care when using your DSLRs for video. Often the sensors are not adequately cooled for long term usage as a video camera (>30m). You have the potential to damage the sensor if it is not designed for continuous use and doesn't have proper thermal protection. Newer cameras will shut down if they get too hot, or have limits to how long you can run in video mode. Stackoverflow discussion: https://video.stackex…

Old wives tale. Even the stackoverflow answers say as much. Most of the thermal ramping occurs in the first five minutes and then stabilizes after cache is exhausted. As all these dslr’s allow you to record 29m50s videos back to back all day long it’s also indicative that it’s not a big enough issue in returns to warrant addressing in their firmware. As you’re not writing to the SD card, hdmi passthrough should yield…

Correct me if I'm wrong, but the 30m limit is due to some taxes or regulations on "video cameras", right?

Edit: Yup. https://petapixel.com/2012/05/21/30-minute-video-limit-in-di...

At the end of the day, it's just a calculated risk and this is one opinion on one side. My DSLR was quite expensive and I love using it for photography, so if there is any risk of damaging the sensor I will not be taking it. YMMV.

Why not use Canon's own EOS Webcam Utility? https://www.usa.canon.com/internet/portal/us/home/about/news...

Fujifilm has also released their own native webcam utility for X and G series cameras. I think it only happened a week or two ago.

The Elgato Cam Link is worth checking out if you're serious about this - it's an HDMI video capture device which presents itself on the computer end as a UVC compatible USB webcam and will accept the HDMI streams DSLRs usually send. They're expensive though. There are other similar devices on the market too but not sure how good they are for this situation.

They're all bought out by price gougers. I've been trying to get one for two months but won't pay $400 for one.

Even before that they weren't cheap though. The RRP for the camlink 4k is USD129 I think - more expensive than a typical 1080p webcam.

curious.

what would it take for you to be convinced it does no harm? Just a psychological curiosity -- not trying to annoy you.

The opinions seem fairly stacked, and the corporations seem to be fairly non-chalantly enabling video/high-volume sampling on these sensors.

The only person in your linked SO thread said "it might wear out the sensor because it wasn't designed for that amount of sampling", so one google's 'Can you wear out a CMOS image sensor from over-use?', and get linked to another SO thread where it's more-or-less concluded that the CMOS sensor doesn't wear practically.[0]

I can understand the 'calculated risk' mentality, but honestly it seems like physical jostling from unpacking the equipment from its' case or exposure to a mid-high level humidity environment, stuff that's done every day by photographers around the world, would be many times more damaging to the investment that just running the solid-state components more often.

Not many DSLR appliance failures are from solid-state device failures.

Reminds me of those light trucks that get ripped apart to create passenger cars.

EDIT: I had it backwards. The tax is on trucks and it gets circumvented by importing them as passenger cars: https://en.wikipedia.org/wiki/Chicken_tax

When I read this I ran to get my camera and my computer!

First downer: My X-T20 is not supported :(

Second downer: Windows only?

So sad right now :(

You can also use Canon or Sony's camera software and window capture it in OBS.
