So what is it that is expected to fail or need replacing after a cameras expected life span.

I know many units exceed their expectations etc etc but what is it that is expected to fail first and how much is it to replace in say a 5D mk111 after 150,000 ?

Thanks

You might as well count on a repair for the mirror assembly and/or the shutter curtains over the sensor, usually the latter. Prices will most likely be around $250-350 USD based on members' previous posts.

MTBF lifetime is a bit like human lifetime expectancy...it is a STATISTICAL lifetime and has nothing to do with actual lifetimes of 'the average person'

So if shutter life is stated by Canon to be 150k, it does not truly mean that you would count on the average shutter to die shortly after it attains 150k....in reality some might have died within the first 1000 actuations, and some might last 500k or more actuations!

In the US the overall life expectancy, for someone born in 2015, fell from 78.9 years to 78.8 years! And Social Security payouts are based upon assumptions of payouts to 78 years...some folks die in the first month, some live 20 years, some live to 103 or later, but 'on average' they die at 78.

I suspect the question is in relation to buying a high usage 5D3 at a low price, and rooey just wants to know what might fail after extended use and what that cost might be as a ballpark. I think he/she knows that the failure statistic is just a statistic, and didn't suspect that the camera would stop working after that point.

Location/Country of the thread starter comes into play here though, costs could be much greater in other areas of the world, and shipping costs higher, than what we might experience here in the US. I am not sure what Sydney owners face with Canon camera repairs such as this.

I always pictured a lab set up with rows and rows of randomly selected Mark III's all being clicked until failure occurs, and they log those and average out the life span. I got this idea after seeing the commercial for Samsung Note's being tested to make sure the batteries don't catch fire in your pocket. None of the Samsung Notes in the lab were in a simulated pocket, though.

Mean Time Before Fire?

They just need the shutter assembly, and could easily put several on a test bed and rapid fire them all until failure.

My friends 7D failed (got sluggish and you would often see the curtain or black bar in the images) at about 151k.

Everything is expensive when you live on an island...

Thanks for the response you got it in 1.

I can at least now price the suspected elements most likely to fail with age and weigh it up.

Failures are entirely inexact. Sometimes problems occur intermittently and only above certain shutter speeds. Sometimes failure is sudden and total. Sometimes it's catastrophic as shutter blades can scratch the sensor. (actually glass above the sensor)
Expect to pay about double (in Aussie dollars) compared to US costs (in US Dollars) if using Canon.
Personally, I'd go to Ziad at Works Perfect in Sydney CBD. I have had work done by him, also a couple of friends that I recommended him too. One took his 1DX which was not working after some water ingress. After it turned on every day at the repair shop for Ziad (and worked) he returned it to owner, no charge. Shows honesty.
I like that you can speak to the person who does the work and you can hand deliver your equipment. No option with Canon but to ship it and they have a Chinese wall in place to prevent any communication with the techs.
