Yes
Hi all could the constant use of video mode cause deterioration of the sensor of a DSLR such as Nikon 7000 series?
 
Watching with interest as I was going to buy a 5d mk3 off a video guy. It has recorded 1000s of hours of video but he has never taken even one still image with it.
 
'Constant' is limited to the max recording time available, which for DSLR's is limited for tax purposes so they are not classed as video recorders.
There is no reason to believe that Nikon, Canon et al would produce a camera with the built-in ability to self destruct ... they are widely used by, for example, wildlife photographers to record video footage.
 
Surely it would the shutter, that there would be a concern with, not the sensor?
 
Yeah I agree but is 100,000 shutter clicks just wearing the shutter out or is it wearing sensor out as well! Totally agree with question !
 
I think the sensor, will greatly outlast the shutter, so don't see it as something to be concerned about.

Self destruct!!! I wouldn't bet on it!!!! Who's bought a kitchen appliance that breaks down a week after the warranty runs out?
 
Video uses an electronic shutter :)
 
I was going to bid on a camera the other day, seller said it was a very low shutter count of probably less than a hundred. Found out from his youtube channel, he had been using it for about a year, and for long non stop video.
 
Look CCTV cameras have electronic shutters and work for years without any sensor degradation.

I work in industrial imaging and have deployed cameras inspecting 100,000's of parts a day, many of these are happily working 10 years down the road. If they fail its because of other issues, eg network interface or on-board memory issues (which happen with any 'computer'

The only time I've encountered sensor degradation is with cameras in the nuclear industry, where the radiation causes lenses to brown and knock out pixels over time.

A mechanical Shutter is prone to failure, as any mechancial device is.

The sensor will almost certainly outlast your time with the camera. I would have no hesitation in buying a camera that had a lot of 'hours' of video recording. In reality its just effectively a computer at the end of the day.


I would say though that long non-stop video in consumer cameras does cause them to run warmer than usual, and as long as they have been designed for this purpose there will be no issue.

Great advice! ........
 
Evening all. New here but thought I'd chip in with some reassurance.

We use a handful of Canon 5D MK iii's (running Magic Lantern to disable their auto shut-off) along with several times that amount of Blackmagic Cinema Cameras and Production Cameras.

Between recording in-camera and sending HDMI signals, I'd say their sensors are in use 12+ hours a day, 300+ days a year.

In nearly 3 years. I'm yet to have a camera fail (and it gets VERY hot in the studio). Plenty of capture cards, PCs and monitors have been cooked or developed faults over that time period but touch wood, not had a single camera issue.

Based on that experience, i wouldnt worry about any damage to the sensor as long as the camera is working fine when you try it out.
 
I work with digital medical sensors and its know they will loose there sensitivity to exposure over time, I wander if its the same with video use, that they need more light than when new. Also do they develop a colour shift from long use and heating?
 
My thread was not about the shutter but the effect on the sensor. My reason for the query is that there is a D7000 for sale in Cash Generator and it comes with lots of video equipment, giving me to think it had been used mainly for video. I took an SD card and took a couple of images to get the shutter count. The shutter count was under 6000, I did notice however that the image quality was not up to Nikon standards and was even bettered by my Samsung compact. For this reason and that the vendor would not negotiate on I deal I did not buy.
It got me thinking that in video mode the sensor pixels must change their state thousands of times more than in normal picture mode hence the question.:thinking::thinking:

I would doubt the sensor would deteriorate, most likely if there was an issue, it would be with stuck or hot pixels, etc. or the sensor electronics failing to work.
Regarding your testing, there are a lot of factors that can determine, the quality of an image. Without knowing, the exact setup you used, it would be impossible to comment. How did you review, the images you captured, via the lcd screen? Could have been an issue with the lcd screen, rather than the images actually captured, but as said difficult to gauge without knowing exact setup.
