Thread: 7D double shutter actuation

  1. #1

    7D double shutter actuation

    I'm starting to notice, that at random my 7D is taking 2 exposures when I shoot.
    the AF settings are on one shot & the drive mode is on single shooting as well

    any ideas ?

    Is it set on raw + jpeg and therefore recording a seperate image in both formats ?

    I would totally agree with the above comments I own a 7D as well. That is prob the most reasonable explanation.

    There would be something very wrong happening if the camera was taking 2 exposures to get a RAW + JPEG image recorded. The saved RAW and JPEG files only happen from ONE shutter actuation.

    How do I know this? We have 2 Nikon bodies that spasmodically take 2 images from one shutter actuation and they definitely aren't in RAW + JPEG

    I agree if in raw + jpeg both images are from one actuation. I offered it as an explanation as to why there maybe 2 images showing up.

    If it is in fact 2 seperate exposures, and not 2 of the same images in seperate formats, then yes something is amiss.

    perhaps my wording could have been clearer and also the op might confirm if it's 2 different exposures, or 2 copies of the same.

    I've just tried this, both Jpeg & RAW are taken from the same shutter actuation

    I didn't mean your finger, I meant the button itself may be dodgy.

    Very strange. Only thing I can think of is the button itself is dodgy. Any chance some moisture or dust has got into it?
