more on Canon actuations

->> As R. Grabowski pointed out in a previous post, the number of actuations reported by Photo Mechanic, or other utilities like Can Count, can be skewed by copying settings from another camera. If you "Save Settings" and load those settings into another body, the Custom Functions, Personal Functions, Photographers Name, and yes, the reported actuations all get transferred to the second body (something I do when using a pool camera or when getting a body back from repair). There is also a seperate counter that can only be viewed by Canon in their repair facilities. This is the "real" actuations, and can only be viewed by Canon or, when replacing a shutter, be reset to zero.
If you have owned a body from the start, and never replaced a shutter, and never copied settings from another body, those two actuations should be the same, as I understand it after several discussions with Canon tech. But if not, the actuations reported in Photo Mechanic, etc can be significantly higher or lower than the actual usage.
The point is, unless Canon repair tells you the actual actuations, a buyer of a used Mark II, for example, cannot use these numbers as a reflection of the life of the shutter. It is likely to be totally different. |

| ->> Thanks for the info Robert. I didn't realize using the Save and Load Settings transfered this information. Looks like only one of my bodies is accurate...too bad I can't remember which one I used as the "master" to copy my settings from! |

->> Why is this such a secret? You would think this would be readily available info so people buying used would have accurate info, and original owners would know when it's time to change shutters. Imagine your car w/o an odometer. There should be a custom function one could access to get the count instantly. I don't get it.

->> Thanks for the post Robert, this helped me get a better grasp on my actual number of actuations.
Since December, I actually loaded the recommended SI settings (found on this message board) twice on my Mark II. The first time, I didn't realize that the auto focus settings for SI changed to the back of the camera, so I reverted back when I couldn't figure out how to auto focus at the game. Looking back at my images, the number of actuations changed to what I think is 529 (I may have deleted test images) after the settings were uploaded.
Thus thanks to this thread, I was able to go back to the image just prior to both of those changes, and determine a more realistic number of actuations on my camera. |

->> I bought a late model 1D about three weeks ago. The seller said the camera had just under 30,000 actuations on it. I had no reason to doubt him as he was the original owner.
In the meantime, I downloaded three different exif readers--Opanda, ExifRead and 1dCount.. I never save any info.. I compared the count from all three readers and they affirmed the just under 30,000 count.
I've shot a total of 459 pictures with the 1D in three weeks according to the latest count of each of the readers. |

| ->> I can't imagine changing my shutter if it was still working no matter how many actuations it did or didn't have. It's just throwing money away. To use the odometer setting, I wouldn't throw out a working motor just because the odometer read 150,000 (or any other arbitrary number). |
