How does using video affect shutter life ?

If one is looking for, say, a used 5diii, one of the things to look for obviously is the shutter count. But I was wondering--if a dslr was used solely for video, it might have very few actuations but have been extensively used nonetheless.

My question: if shutter breakdown is just what generally happens when one takes A LOT of photos, what happens when one uses video a lot ?

I have nothing to back it up, but I would suspect a single video regardless of length would be the same as a single shutter actuation. You don't count a 30 second exposure any differently than a 1/8000th of a second, why would you count a 3,000 second exposure differently? There's still only 1 movement of the shutter per video, not 1 per frame of the video.

Heya,

Ever used a DSLR for video? Do you hear the shutter actuating and the mirror slap?

Very best,

It was discussed here before:

Since then I read somewhere (and can't find it right now, Google-Fu is not working) that claimed that there was increased wear on the shutter when doing video as the shutter is designed to stay closed and only open momentarily. Said article implied that keeping the shutter open caused extra stress on the shutter mechanism.

If I can find it, I will post.

I don't see how this is helpful.

I can't imagine there is any significant detriment to using video, aside from heat build up. I don't know if prolonged video can damage the sensor or not as I've not heard anything indicative of that. I use liveview for extensive periods sometimes, enough for the heat build up to feel significant, and I've not noticed any lasting damage. No excessive amount of stuck pickles or peeling grip.

Thanks guys.

My concern would be issues arising from overheating over time, though I have no basis for presuming that this actually occurs.

It just seems intuitive to me that the more you use something the more likely it will be to burn out. The challenge with video is that it doesn't actually register on the camera as an actuation and so there really is no telling how much a camera has really been used.

In theory the sensor could heat, but that wouldnt have any effect on the mechanical shutter.

If you're concerned about heat, read post #6 from this thread:

@gonzogolf: My concern isn't just with the shutter, it's with the overall life of the camera.

Thanks a lot.

I agree with the others, the overall life of the camera should not be affected adversely with extended video usage

Very best,

You hear the mirror go up when you enter video mode with is similar to going into Live View.

I don't really know how much heat is being added when taking photos, but I have never felt my camera heat up. However, when recording video/I also shoot raw video with magic lantern on my 5DIII, it does heat up. I would think that any type of heat for prolonged periods on the cpu/motherboard would eventually wear out the system (the same idea applies to computers). However, the camera knows when to shut down when a certain heat threshold is met.

You can actually check the shutter actuations and live view actuations using magic lantern.
