Anyone want to comment on this? Not that it really matters but I hate mysteries. LOL

Found a program on the internet, cost me $5.18. Displays shutter count and mirror count, although I am not really sure what mirror count is as it is 4667 higher than the shutter count. When I take a shot the shutter count and mirror count increment by 1, as I expected. When I do live view or video both shutter count and mirror count again increment by 1. Shutter count is 6936 and the mirror count 9269. Have not figured this one out yet. I bought the camera from an older gentlemen, who told me he was the original owner. Camera is about 2.5 years old so I have no clue how the mirror count got so far ahead of the shutter count. Unless this camera was purchased as a refurb after a defective shutter was replaced. In my mind, the shutter and mirror count should be the same. Bottom line is camera was not used much, is mint and looks unused plus works perfectly so I do not see this as any kind of issue. Just curiosity ........ This is my first Canon DSLR. Sold my Nikon D700 and I do not regret the change. Love the Canon 80D, especially the fully articulating touch screen and SD card. No more Compact Flash!

Mirror lock-up only, no shutter use???

Live View? no shot taken?

No. The shutter and mirror both advance by 1 for each time a shot is taken, even on live view or video.

Does just the act of turning the camera on then off change the mirror count? Can't think of why it would, but it won't hurt to check. Otherwise, I would suggest you un-install your shutter count program and find something else to add mystery to your life!

No, powering on and off has no effect on the shutter or mirror count. Not an issue with me, just curiosity as to how it happened. If both counts increment the same they should stay the same. Unless Canon is different from Nikon, when I had the shutter replaced on my D300, the shutter count was never reset but the original shutter count was noted on the invoice. Like a said, PURE CURIOSITY. LOL

If it did it might be the auto dust removal bit, shakes things to get dust off the sensor, might move the mirror too.

Probably just like me. A little old gentleman that only takes his DSLRs out on Sunday for a ride in the country, grin.
Seriously though, the previously mentioned use of "live view, "mirror lockup", a defective program, or even a scam involving $5.18 could explain your mystery.
Good luck with solving your mystery and your photographic journey.

Your reply didn't answer the question, so here it is again: "Mirror lock-up only, no shutter use?"

authorizeduser Loc: Monroe, Michigan

I could believe this may be an explanation if it were only 40 or 50 but not 4667 times. I also thought maybe the shutter had been replaced but the few times Nikon replaced shutters for me, the count was never reset so that theory is most likely not valid, unless Canon resets the count.

Is the data accurate? Is the data relevant? When was the last time you saw anyone ask to see the 'mirror count' on any type of camera? If you're bound and determined to get an answer on something that doesn't deserve the attention, call Canon and ask them. And, be prepared to be told they don't support 3rd party software, and instead, pay to have the camera sent to them for an 'official' reading.

Maybe he shot video a little and ther in lies the difference?

PGHphoto Loc: Pittsburgh, PA

The mirror count is incremented any time the mirror goes up. If used for video, the mirror count will always be higher - thats why Canon shows both. Try shooting video with no stills taken and see what you get.

Hard to say.

If those numbers are correct, the mirror count is 2,333 more than the shutter count, not 4,667. Hope that figured it out for you.
