Vatche Giragossian Posted October 16, 2019 Share Posted October 16, 2019 Im looking into purchasing the ARRI ALEXA High Speed Camera Body. The camera has 4000 hours of sensor hours. My question is, is that a lot of hours? and what is the average cinematic camera sensor life span? Link to comment Share on other sites More sharing options...
Max Field Posted October 16, 2019 Share Posted October 16, 2019 Someone told me the sensor is rated for over 50,000 hours. Link to comment Share on other sites More sharing options...

That sounds a lot, but well-made solid state components can last a long while and Alexas are good at avoiding over-heating. The sensor is of course only one part of the hardware chain that creates an image, so there are other components involved. In our local inventory sample of about 10 Alexa Classics or XTs the average would be about 5000 hrs. The hardest worked one has logged nearly 8000 hrs. Over time a sensor can accumulate dead pixels or simply age so that the image between cameras can vary. On multiple camera shoots sometimes one camera might get rejected because it looks a bit different from the others, due to hardware aging, but on its own the camera is fine. I'm not sure how it would look after 50,000 hrs though.. Doing things like shooting straight into the sun can damage a sensor, or poor cleaning can scratch the cover glass etc, so it can depend on how the camera has been used and maintained, but I think 4000 hrs is certainly not excessive.
