Canon 7D MK II high shutter count

I’ve just bought a 7D II, it has nearly 200,000 shutter actuations. I know the life span is meant to be 200,000 can I expect more if say how many as it will only get light use.

Anyone had a 7D II shutter replaced? If so how much and where. I am still a CPS member.

BTW just getting back into Canon after being away for a loooooong time.

There is no life span for Canon cameras, they just publish the results of stress testing on their gear to create a Mean Time Between Failures number for each model.

You just keep using it until it breaks, then worry about the replacement then of the shutter/mirrorbox at that time. There is no way to know when that is. Some fail at 10K, some fail at 500K.

I'm in a similar boat- I think mine was ~226,000 when I bought it in January. I've put another 10K on it since then, and never a hiccup.

The shutter life database is sometimes helpful, but it actually paints a pretty bleak picture for the 7d2: http://www.olegkikin.c​om …fe/canon_eos_7d​_mk_ii.htm
(Compare that to the 5d2, which had a 150K rating: http://www.olegkikin.c​om …rlife/canon_eos​5dmkii.htm )

Shutters are a funny thing. That rating isn't a guarantee, and it really doesn't make sense to me. SOMEtimes if you're well under the rating, I've heard of Canon USA replacing shutters for free even if it's not technically under warrantee, but they're not obligated to, and they often won't. And I'm pretty sure that varies by region. But yeah, sometimes shutters will go well past the rating, sometimes they'll die early. But the thing is, if you get it replaced before it fails, there's no saying your camera didn't have a shutter that would've gone to 500K, and they'd replace it with one that'll die at 80K. Some people actually like high mileage cameras, because they think that if it made it over 200K it's more likely to go really long. I'm not sure there's any evidence for that, but I'm starting to think there's something to it. Heck, my 5d2 is at 165K, my 7d2 is now at 236K, and I just bought a 5d3 with over 200K.

I did send my 5d2 to Canon for a checkup, and they wanted to replace the shutter just because it was over the rating. I told them no, but they did quote me $350 for parts & labor. So that probably gives you a ballpark figure on what it would cost...

Excellent that’s just the answer I was looking for, thanks.

I am not sure why that is a bleak picture?

Over 2/3 of the reported 7D2s are still active at 200K clicks... Doesn't drop to 50% until about 3x the clicks on the OP's camera.

Don't rely on anything in this site. It's a complete joke. There is no attempt to validate any of the data. I'm not sure if it's still being updated but you can send in some ridiculous number like 5,000,000 and still going strong and greatly sway the data.

It's quite simple really. Canon takes a bunch of cameras or maybe just shutter mechanisms and beats the snot out of them. From failure analysis they calculate a number (MTBF) where if reached, 50% of the test pool failed and 50% of the test pool are still functioning. There is no way to extrapolate that number to a specific individual camera and predict when it will fail but basically, you have a 50%/50% of reaching the rated shutter number. If you buy a high shutter count camera, the odds of failure greatly increases but without seeing the whole gausian distribution of all failures, you really can't estimate what your odds are.

To me, the top of the chart is the part that looks bleak for the 7D2.

If you total up the "alive" shutters and total up the "dead" shutters for the top 7 lines, you get a total of 14 cameras with good shutters and 10 cameras with dead shutters - within the first 10,000 clicks!

Heck, one camera's shutter was reported to have died within the first 100 clicks .....
and 5 out of 10 died within the first 1,000 clicks ...... unbelievable!

If those statistics are true, then to me, that is an astounding percentage of dead shutters that happen within just the first few months of use.

I'm thinking that these stats must be false, or at least not representative of the whole population of 7D2s.

True about the validity of the data. I guess it didn't occur to me that some people have nothing better to do with their time than enter false data on a tool designed to be helpful...

I was also under the impression that the shutter ratings weren't really MTBF. Maybe I'm confusing the source of the number with the application of the number. Because like you said, if it is MTBF, that doesn't really have much predictive power.

Huh. I was looking mostly at the listed average number of clicks on dead shutters, which is less than half of the rated shutter life. And 1/3 of the reported cameras failed in the 10K-35K range. I'd need to review my stats and see what can be made of this kind of data (although as it's been pointed out, the data source isn't all that reliable).

Agreed.

When 40% of the cameras die within the first 10,000 clicks, and 1/3 die between 10,000 and 35,000, that would seem to be a very bleak picture to me.

So those statistics do seem to say that the 7D2 fails miserably when it comes to shutter life. . What other conclusion can one possibly draw when looking at the number of cameras that fail before they even get 35,00 clicks on them?

But of course those statistics must not be true, because if they were true, then there would have been this enormous outcry over the 7D2 shutter life that would have had a huge impact on Canon and the camera industry as a whole. . It would be one of the biggest "epic fails" in manufacturing history! . Of course we have heard of no such thing, so I would have to believe that these stats are just false made-up crap.

.

Canon's numbers have to be related to MTBF numbers, else they mean nothing. They randomly pull shutter units from the line and hook them up to actuator counters and tally up counts vs failures. Not sure how they check for a bad shutter blade vs a completely dead shutter though.

Also "life expectancy" that is quoted is often analogous to MTBF, especially when talking cross-brands.

We also don't know if people know the difference between a failed mirror and a failed shutter.

It's not reliable in any way especially the "alive" category. For example, some idiot reports that their shutter is alive at 100 clicks. Do they then update it when it reaches 2000 or 10000? What does the data even mean? Or more likely, someone reports that their shutter is alive at 100 clicks. Goes and shoots a bit more, then reports that there shutter is alive at 200 clicks. Repeat for 500, 1000, 2000. So, are all the "alive" cameras that same person just giving us a weekly update?

And then you have a bunch of cameras that don't even have shutters like the Canon PowerShot A85. How do you have a shutter failure when it doesn't have a shutter? Are we counting anytime that the shutter button is pressed and it doesn't work as a shutter failure? If so, then maybe the failures are shutter button failures, or battery failures, or motherboard failures. There is no confirmation that the failure was truly a shutter failure and not something else.

The site is beyond a joke, it's misleading anyone who tried to get any meaningful from the data. It has so many flaws in the way the data is gathered, in the way it's validated, or even on how it's defined. Ignore it.

Used 7D mkII are getting cheap on the used market, I wouldn't worry about it. BTW were you on the old Photosig site?

Of course!

Any data that is crowdsourced is pretty much worthless for most things, because there is typically no way to control any of the variables, and no way to verify the information that is being reported.

We're just having fun discussing it, even though we know that it is useless. . What else is there to do on a lifeless December morning for someone with no motivation to do anything and gobs of time on his hands to fill up somehow?
