Nikon quit selling Nikon parts to independent service centers in 2012 and now they will not be selling anything to their authorized service centers. Can only image why they would make such a dumb move.

No, Nikon is NOT so good they do not have service issues like anyone else.

Can you please move this to Main Discussion area? i do not know how i posted here .............

This is not good. I have been a Nikon user since I got my first DSLR. Was in the market for a new camera and after seeing Nikon decision, I bought a Canon 80D. At least I can take it to an authorized service center if needed and not have to pack it up and ship it to Canon. I live within driving distance of Midwest Camera Repair in wyandotte, Michigan. I have heard the stories that Nikon has extended turn arounds now, so I can imagine what is coming with only Nikon California and Nikon New York available. So long Nikon, hello Canon.

Thanks to all who have commented. Was never an issue, only a curiosity as I have never seen a mirror count before. I am happy either way. The camera is in new condition, low usage and works. I am satisfied and will go out, take photos and enjoy.

This is true. Anything which moves will eventually wear out depending on its use, quality and durability.

Your right. My math sucks! LOL

This is the first camera I have ever seen a mirror count on. I do not care one way or the other so long as the camera works. Was just curious.

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.

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

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

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!

Because they can

When in live view the mirror flips up I understand but does the shutter actually activate? If it doesn't that would explain why the mirror count is a whole lot higher than the shutter count.

.

Problem solved. Paif $5.18 and bought EOSMSG. Works fine bit is limited on to this camera. No Problem.

It does show a shutter count and a mirror count. Now I noticed, after taking a photo, they both advanced one. So just how is the mirror count ahead of the shutter count? ARRRGGGH!
