Shooting video cause damage to dslr

[lingaesh]

Hi.. Guys,
Am Lingaesh from India. yesterday i went workshop, the trainer said that SHOOTING VIDEO IN DSLR KILLS DSLR LIFE VERY SOON BECAUSE OF ITS GETTING TOO MUCH TEMPERATURE OR CAUSE VERY SERIOUS PROBLEM TO ITS SENSOR AND COMPONENTS. i want to clarify this with you guys, please MAKE ME RIGHT SENSE. I own canon eos 70D.

2. Then i heard about SHUTTER EXPECTANCY, what is it, and how its affect my cameras image quality. Whats the shutter life of canon eos 70D

[Dave Humphries]

Personally, I wouldn't worry about either.

That said, if you're in a much warmer ambient temperature than I am, and shoot video and leave the camera on a tripod in full sunshine, then it might overheat. My Nikon D7100 shot my daughters wedding a couple of years ago and it was used for video for several batches of 20 minute shooting time and it has survived OK.

In regard to shutter life; as long as you don't 'waste' clicks, e.g. do not sit there just listening to it 'machine gunning' at 10 fps for minutes at a time because it sounds 'cool', you shouldn't need to worry about it.

Anyone else?

My personal opinion is that any camera which is not designed for Video should only be used sparingly.

I tried to make one 15 minute single run video of a presentation with my P7100 and was alarmed at the heat it generated. I then experimented with my V1 and DSLRs and also felt them get very hot. This is not generally a good thing.

The idea that folks shoot full length shows with a DSLR ignores normal video production processes with many, many short cuts editted together.

I did have a Canon video camera that cost less than most of my DSLR lenses which gave great results and never got hot to my hand even when used with AC power for a half hour presentation.

1. I would suggest that what the trainer said is pure garbage and is purely his opinion, rather than anything based on technical analysis. Yes, the electronic components do warm up when shooting as there is electricity flowing through the sensor and the camera's electronic components, but the same thing happens with a purpose built video camera. The engineers that designed your (or any other camera) will have taken that into account. Unless there is a specific mention of a duty cycle in your camera manual (i.e. do not shoot longer than a specific amount of time before letting it rest for a specific period), then there is nothing to get worried about, so long as you are shooting conditions that fall in the design specs of your camera. When I look at my camera manual, I can use it from 0°C - 40°C at humidity up to 85%. Your camera may be different, so check in your camera manual.

2. Shutter life expectancy is just a measure of how many cycles a mechanical shutter is designed to last. If the shutter breaks, you won't be able to take any pictures. The technical specs for your camera should be on line somewhere, but you are likely looking in the 100000 range.

The shutter count expectancy is c. 100,000 -here are a couple of urls for you;

It doesn't affect IQ; the camera works, until it doesn't. For most people, they will have replaced the camera long before the shutter fails.

Regarding the temperature reached, it depends on the ambient temp; I have shot video lasting several hours, but from an ambient temp of c.25 Celsius. I use Magic Lantern for video, which includes temp readings.

What is the ambient temperature for you?

I prefer to shoot my video with a dedicated video camera. I am not keen on shooting video with a DSLR...

A secondary thought; perhaps the trainer has an affiliation with a local camera shop that sells 'proper' movie cameras

Canon specs indicate that the maximum recording time is 29min 59sec. Some commentators suggest that this is meant to protect the sensor from overheating. Not have recorded much in video I can't comment, but the ambient temperature is definitely an issue for sensor performance.
I have seen images of customized bodies for astro-photography (involving extremely long exposures) that have had cooling mechanisms installed to improve thermal performance and protect the sensors.

That is one of the saddest stories going and something I understand we can blame the EU for. The duty rates for still cameras and video cameras are different and the moment a camera is capable of recording 30 minutes or more of video in a single shot, the higher video camera duties apply. In order to get around that purely arbitrary decision, still cameras are limited to 29min and 59 sec.

It sounds like your trainer is talking utter rubbish - lets change the scenario slightly and talk about mirrorless cameras where the sensor is running all the time regardless of whether it is taking a picture or just displaying the image on a screen to view.

[Tronhard]

I agree that under normal circumstances it should not be an issue. The specialised cooling systems in my post were, as I said, for EXTREMELY long exposures (up to 10 hours apparently) used in astro-photography, and I can't imagine anyone doing that in may other applications... Also I would suspect that DSLR cameras may not have the means to dissipate heat the way MILCs do, but that is purely conjecture.

From the manual it appears that the camera will automatically shut off if the internal temperatures get to high. An icon shows a white exclamation point at which still photographing should cease, and a red one for video, as image quality will suffer. The red icon shows that the camera will shortly shut off. Shooting at a high ambient temperature will cause the white or red icons to show up earlier. Turn the camera off and let it cool. Page 287

Probably more of a problem if you leave your camera in full sun, or in a hot car.

Also suspect your trainer was talking garbage.

[lingaesh]

Thanks Mr.Proseak, am from India now we r in winter season son the temperature is 27 degree, in summer we experienced above 35 degree.

coming to ur answer, ur saying that AMBIENT is plays main role to increase cameras temperature, am i right

Hi Mr.Ken, I afraid when i heard his words, and i thought "I SHOULD NOT USE MY EOS 70D FOR SHORT FILMS" , So not gonna damage my cameras sensor or components if i shoot video in my EOS 70D

Thanks Dave, Come to ur answer, I dont hurt my DSLR by shoot video, if i used in low ambient temperature,

Forget about shooting times.
Forget about ambient temperatures.
Forget about the rubbish your tutor was talking.

You won't damage your DSLR by shooting video.

It has nothing to do with lowest ambient temperature, so long as you are working in the operating conditions specified by the manufacturer. DSLRs have been DESIGNED TO SHOOT VIDEO. This statement has been true for over 8 years, as many DSLRs have had this feature starting in 2008, when this feature was first seen with the introduction of the Nikon D90.

When something has been designed for a specific purpose, the manufacturer would have ensured that this use was taken into account when the camera was designed. It would also undergo extensive testing to ensure that the camera operates properly in the conditions it was designed to operate under. Safety devices like thermal cutoffs would be incorporated into key components to ensure that do not exceed their design conditions. If there was a problem out there, I'm certain this issue would have been picked up by some photographic publication and the world would have been made aware of it. I don't ever recall reading anything like that anywhere.

Robin is quite right - when you turn on LiveView, your camera is operating in the same mode as when shooting video. The sensor is on, the shutter is open and the data feed goes to the camera screen. If you look at the camera component that uses the most power (which in turn generates the most heat), it will be the screen on the back of your camera body. It will also drain your camera battery the fastest.

The only negative I can see in terms of what the heat might do is to introduce more noise into the image / video. So shoot at base ISO (or as close to it as you can), and that issue is easy to control.
