Shuttercount

Hi Guys

I just used PhotoMe to look at some of my shots. I checked image 7500 and and showed 7835 activations, 7400 showed 7735 and 7100 showed 7434. Then just for fun I looked at my earliest image number 0002. PhotoMe said 229 activations.
So there must be some form of factory test.

Cheers from Oz

cool, was hoping there was a better way than keeping track of the number of images in 10,000 groups.

I have used the preview occasionally so would expect the IMGnnnn to be different, and it is but by more than I would have done.

Last IMG2770.JPG (so #12770)
EXIF data reporting Shutter Count of 13001

Interestingly the Date of Manufacture is saying 2005:12:03 That can't be right!

Cheers, Nige

I still haven't managed to get shutter count from *Ist DS jpeg (converted from raw with silkypix)
Try to run it against JPEG/PEF files taken straight out of camera.

If you think about it, it makes sense.
Of course there is a final quality control to check (and probably) calibrate many many things like: auto focus, sensor, shutter mechanics, exposure, colour settings, etc. etc. Not for nothing there is a support / maintenance mode in camera.

I've managed to get correct shutter count from *ist DS jpegs, PEFs and DNGs (converted with Adobe DNG converter). DS firmware ranging from 1.00 to 2.02.

However it seems that jpegs converted in Lightroom, Photoshop, doesn't retain manufacturer notes and shutter count can't be extracted from files, processed with those programs.

Good to know I can get accurate shutter count for my camera in case I sell it and in case I buy used

I wouldn't rely too much on these results. Only people with dead shutter should contribute.

IMGP1614.JPG

Shutter count = 994

isnt that wierd?

hmm now that i think of it, could it be because i used the same memory card in my K100D? that had about 1100shots?

Something to think about for all those who's shutter activations exceed the image counter (and who have not reset the image odometer)

Does the opening of the shutter during sensor cleaning count?

How is your camera programmed. Sensor cleaning at startup ?

Just a thought

I've got a few questions along this line. When you're talking shutter counts and shutter life what is it that you're talking about wearing out? Is it the actuator that flips the mirror up? Is it the one that closes your aperture? Are these one and the same or, if not, how does the lifetime of these differ?

I've got a K10 and I use a lot of old lenses so I'm stopping down to meter a lot. This topic always make me think of the disparity between the count of photos recorded and actual aperture (perhaps shutter?) activations. I'm at 4000 photos taken but add in metering stop downs and I've probably hit 6000 aperture activations. That's a significant difference, especially as the number of photos taken grows .

> Shutter count = 994

Could this relate to my questions above? If you shoot a lot in Av mode with manual lenses the aperture isn't closed down when you shoot. Does shutter count increment on aperture closures or mirror flips?

Shouldn't be too difficult to test?

The fine name IMGPxxxx tells you how many shots you've taken. Once you get to 10,000 it goes back to 0001. Just keep a log of 10,000's if you really wanted to know.
Actually it doesn't reset, the filename prefix is changed after IMGP9999 to _IGPxxxx (so the next shots would be _IGP0000, _IGP0001 and so on, not IMGP0000, IMGP0001 all over again).

I'm not sure how the prefix would continue to change after the 19,999th shot (assuming it still does).

LCD Depth of Field preview is one situation where the shutter would release without incurring an increment in the image count (as no image is recorded). Will test and confirm...

Wow! Jens Duttke is a genius!
Have you noticed, he also managed to hack AF point information. Now his tool (PhotoME - Exif, IPTC & ICC Metadata Editor) nicely displays AF point on picture.
I just downloaded the latest copy and noticed a couple more neat features:

1. He hacked the AEDump EXIF. This is a dump of each of the 16 meter segments. I have a Jave program that does that. But he has cracked the mapping from the 0-255 raws readings to Light Values.
2. He found the shutter count for the newer cameras. THe *istD and a few after that had a count at makernotes 029 hex. This was dropped in the latter cameras. He found a new counter at 05D hex.

Filename _IGPXXXX indicates that Adobe RGB was used as colour space. It has nothing to do with shutter count.
