shutter actuation question

->> The shutter on my Canon 1dmk2N recently died at 245,000 actuations. Just got it back from Canon, paid $450 for repair, but actuation count is still at around 245,000.
I kind of thought that number would get reset to 000001. Anyone know about this? |

->> What did you use to check the actuations?
Question:
Did the repair involved replacing the shutter?
Canon repair centers tap into the camera to get their number. What shows up in the 3rd party apps often differs.
Another thing I was told once is that when you save camera settings to a card and then load them into another camera, the actuations the 3rd party apps "see" is the number from original camera where the settings came from. Anyone else see or hear about this?
Question:
Do they reset the odometer on a car when the engine or transmission is replaced?
To me, high-mileage ... or 1/4 million shutter clicks ... I'd like to know the "real"number if I were someone that dabbles in buying used.
Question:
Is it fair to say a 3 year old camera has 8,000 actuations because it was reset recently? Or is the 1/4 million shutter clicks that a camera actually do during its life a more honest evaluation of what condition the camera is in?
I guess it's an individual thing. |

->> Also, I guess the number only matters if you're selling the camera.
If not and it's working ok, what difference does it make what the actuations are?
And lastly ... here is an interesting site I came across a while back:

->> No, they don't reset car's odometers when the engine gets overhauled. I guess the actuation counts don't get reset either.
I'm using Photo Mechanic to check actuations. The repair did involve replacing the shutter ($200 in parts, $250 in labor). |

->> Sorry ... this is my last add:
The Mark IIn shutter life expectancy is "200,000 cycles". |

->> Robert, those numbers on that site seem a bit off. I checked the stats for the two cameras I own, and this is what the site claims:
1dsmk2:
Average number of actuations after which shutter died: 2,296,445 (two million? cmon...)
Average number of actuations after which shutter died: 44,450
(that few?)
Both stats are way different than the number canon claims. |

Consider yourself quite lucky. I've had 2 MKII bodies and both needed shutters replaced before hitting the 100K mark (according to PM). The first one cost about $495 to repair (Canon felt it necessary to replace the top plater for some reason).
The upside is I think Canon also replaced the CMOS sensor in the first body to go in. The camera came back in perfect working condition and the soft spots (I had five areas of the frame that were always soft while the rest of the frame was perfectly sharp) were gone. Edge to edge of the frame was sharp and the AF was much more accurate from what I an tell. Several months later the camera became the subject of several photo sites around the world (see my main photo) when it suffered a unfortunate accident.
The second one is waiting to go in for the same service. 245K worth of clicks? I wish one of the cameras made it that far without being repaired. I'd been happy if either made it to 150k in clicks. |

| ->> As an aside, I got my D2H back from Nikon after fixing the shutter and it was reset. Now I have a two-generation-old camera with 1,200 accutatiions. I guess I should start using it again.... |

->> Robert,
Chuck Westfall of Canon USA responded to this question in the forum linked below. It makes clear that exif data is not intended to accurately record shutter actuations. I had read this elsewhere but can't find it now. This exif data is transfered when using the "save camera settings" in the camera.

-----------------------------------------------------
The only thing that this episode shows is that software applications that purport to provide an accurate actuation count based on image metadata don't work. Rest assured that Canon Factory Service can determine the correct actuation count directly from the camera regardless of any attempt to reset it.
