What's your actuation count?

last time I checked both cameras were around 20,000

Carroll, the number on your picture (DSC_7895) will hardly ever represent the actual number of actuations. This is because you delete files/pictures. The surefire way of getting the number of actuations, is to use one of the links that was posted in this thread. For you, it means you have deleted 482 pictures. You know have 91,623 shutter actuations left on your camera before it may start to fail - Nikon tests it at 100,000.

While you are correct with the assertion that the number following your photo name prefix will almost never give you your shutter activations, deleting photos is not one of the reasons. If the most recent photo on your card is DSC_9991, and you took two more, DSC_9992 and DSC_9993, but then reviewed and deleted them, the next photo taken will still be DSC_9994 regardless of whether or not you deleted the two images. The camera keeps a running counter that will only reset when it loops back around to 0000, or every time you turn on the camera if you choose to set it up that way (though I'm not sure exactly why you'd do that - though I inherited one that was set up just that way).
The discrepency between the numbers (in the first 9999 actuations) has nothing to do with deletions and more to do with if and when the naming counter has been reset at any point.
Thank you, I appreciate it. I didn't realize that if pictures are deleted, that they would be "erased" off of/from whatever collects the data for the actuations. That means when you purchase a camera that has been on display, you have no idea how many actuations it has. Interesting.

Not unless you snap a photo and load it into something that will display the full EXIF data while in the store. Sort of a shame that manufacturers actually store it but don't make the data available directly to the person holding the camera.

This does not really jive. So, for example, i take picture 001, 002, 003, i have 3 actuations. I erase those pictures and then take 004,003,006... i have 6 actuations and the picture number represents that. I then take picture 007, erase that then take another picture for 008. Again, the picture number represents the number of actuations. I don't beleive that this is what happens. If it did, then the last picture number on my D5100 which was something like 4600, would represent my actuation count, but it does not. Hmmmmmm

Which is precisely my point. As you should note, my statement says, "almost never". If you are the only person to ever have depressed your shutter button, and neither you nor anyone else has ever reset the image counter, and you have not yet taken your 10000th photo, then yes, it's entirely possible that the numbers will be in sync. But if you walk into a camera shop, grab a body off the shelf, snap a photo and see a DSC_0001 and you have no way of knowing if that's truly actuation #1 or not. Anyone can go into the Custom menus, to the shooting/display section and either turn off or reset the "File Number Sequence" option and the camera will be forever out of sync. But no one has ever accidentally reset or changed anything in their camera menus they didn't mean to, have they?

Not true. What about a camera with two cards? Format one and the other still moves on. And I just tried it on my D90 and sequencing continues. And I've swapped cards in the same camera with no formatting and the filename sequencing continues on as before, so it has nothing to do with the card. At least not with any camera I've owned. If it did, why would so many people recommend reformatting the card as a faster way of wiping a card full of images than using Delete? If it reset the sequence number you'd then have to start dealing with duplicate names on your image files, and isn't THAT a hassle!!
Then perhaps it depends on the camera, because that's how it's working on my D5100. Just tried it again, with the same results.
As for duplicate image names, I organize by date shot so it's a non-factor for me.

Did a quick search and on the D5100 there is apparently an option for "File Number Reset". Unless it's turned "On" this is what happens:
"When a new folder is created, the memory card formatted, or a new memory card inserted in the camera, file numbering continues from the last number used or from the largest file number in the current folder, whichever is higher. If a photograph is taken when the current folder contains a photograph numbered 9999, a new folder will be created automatically and file numbering will begin again from 0001."
So it is not the act of reformatting but the setting of the option coupled with one of the other actions.
I organize the same way, but with multiple cameras and whatnot it's one less way of having collisions. If I reformat two cards in two cameras on the same day, I'm screwed from the get-go. I do everything I can to avoid it, from different prefixes in different cameras, to never resetting the counter. Saves me from thinking about something I shouldn't have to think about.
Ahh. I never touched that setting, and it was off. So either it comes that way or my Dad set it up that way before I received it.
Good catch. Not that it really bothered me, but I can see where it would.
