5D replacement shutter

I didn't think there was an actual limit. As far as I know, you keep using it until it fails?
 
Just use it until it goes pop.

It doesn't die when it reaches the expected actuation, same as cars don't go pop when it gets to 100k miles.

I've seen 5D hitting half a million shots and they still work, don't worry about it, I never check my 5D3 shutter count when i had it, and when i sold it, it had 150k on it.

I've heard about a 150k limit? The issue is, i'm a wedding tog and dont want it giving up the ghost half way through the ceremony (I have a backup camera but still!)

no its not a limit, its just a guide really.

Such figures AFAIK are MTBF (mean time before failure), as noted many shutters fail way over the Canon quoted figure................even the new replacement can fail at any figure from 1 upwards. Is that not why pro togs have backups because a failure can occur anywhen for any reason and they have to mitigate for that, please do not assume that just because you get the shutter replaced that it will only eventually fail at 150K or higher. That is not how the MTBF analysis figures work!

I think the life is rated at 250k for the mk3, 150k for the mk2.
 
Keep at least one extra back up body and then carry on. Pretty sure there are a lot of cameras out there (including mine) that are way above the "limit".

Replacing the shutter doesn't make it sure. In fact, whenever work is carried out on a complex piece of machinery, there's always a chance that the technician will do something wrong. Your camera will probably be more reliable if you don't get it "sorted out".

The textbook example of this phenomenon was the British Airways flight where a newly-replaced windscreen failed because the wrong bolts had been used to install it. The pilot was sucked out at 17,000 feet and was incredibly lucky to survive.

Less dramatically though, I have some relevant data. Since the beginning of 2013, at Lenses For Hire we've sent 514 items off for repair at the manufacturers and 27 of them have had to be sent back to be re-repaired. So that's a failure rate of about 1 in 19 immediately after repairs, which is much higher than the failure rate we experience generally.

:eek:
 
Have a look here for some data on shutter life expectancy: https://www.olegkikin.com/shutterlife/

As you can see there's a lot of variation, with the average 5D shutter life at 125k but some dead less after less then 1k clicks and others still going after a reported 1000k!

I don't have any data, but I'd be willing to bet that the figures for things like cars, dishwashers, etc would be comparable.

I remember reading some motoring advice - don't get your car serviced the day before going on a driving holiday...

The more ive read about this, the more a figure of 150k is mentioned for the 5D3, just to be sure, it's going off to get sorted out at Fixation, don't want it dying on me! :)

Well I hope for your sake it pays off. But I have to agree with Stewart and Richard (who've both handled more cameras than I've had hot dinners), statistically you've not improved your luck.

I was a mechanic a long time ago, and a 10% rate for rework wouldn't have raised an eyebrow.

'If it ain't broke don't fix it' is a famous old motto for a very good reason.
