    Pentax shutter count



    Hello guys.

    Just got my K100D and would like to know its current shutter actuation count. I've used Opanda (freeware) on a Nikon-taken shot and it readily displayed the "Total Number of Shutter Releases for Camera" under the header "Maker Note".

    For my Pentax-taken shot, can't find the shutter count and the "Maker Note" has a padlock icon beside it. If you try to edit it, the info is displayed in hexadecimals...first I don't know which entry represents the shutter count, and next I'll have to review my math to convert the value(s)

    Help please. Thanks!

    Re: Pentax shutter count

    This has been discussed somewhere before and I think that the Pentax firmware does not record the shutter count in the same way Nikon does. EXIFs are not standard in a sense that there are 'undefined values' which are unique to different manufacturers.

    Re: Pentax shutter count

    Isn't the file number technically a record of the shutter count? I passed 10K shots this weekend! My file numbers were 9999, now I'm at 1011.

    Re: Pentax shutter count

    Nothing. The camera creates a new folder, so there are no conflicts in file names. I walk around with 3 4GB cards and sometimes swap around.

    I also discovered the new folder thing because whenever I go to malls and play with other cameras (i.e. D80, 40D, etc.) I stick my SD in for sample shots to compare when I get home. When I opened the drive, I found a bunch of Nikon- or Canon-specific named folders, each including only the shots I took with the respective cameras.

    Re: Pentax shutter count

    UPDATE!!!

    I was playing around with Exiftool

    Guess what I found?!?



    So... Pentax does tally the shutter actuation count, but it's buried in the exif data.

    It even records alot of other things like Shake Reduction (Not Ready, Not Stabilized, or Stabilized), Battery/Grip Load, Lens Data, etc.

    I just don't know if the shutter count data is accurate. The data above is from IMGP1280.PEF. It's off by 2497 actuations. But I think I did a reset before just can't remember. It works for PEFs and JPGs, dunno about DNGs.

    Can I request those who recently bought their new cameras to try and read their shutter count and compare it with their current image number count (ex. IMGPXXXX). Thanks!

    By the way, I tested a few images I took with Randy's K100D and the shutter count data is there too.

    is exiftool reliable? i mean, i know i have turned on Noise reduction. Color space uncalibrated? how do i calibrate? SR not ready? hmmm.. this is weird...

    or i am just stupid..

    here is a GUI version of exiftool, seems everything is in order when matched.
    PLUS this shows the AF area of the photo..
