I'm having an issue where my 1Ds MK III on RAW or jpg will only shoot 2 images at a time and then write to the card and then shoot another image and write and then 2 more etc. The high speed shooting mode is selected.
It does this with different cards and when there's not a card in the camera. It does it with AF turned off on the lens. I reinstalled the firmware. I even reset all of the functions of the camera and it's still doing it.
I first noticed the problem after shooting tethered to DPP. I'm convinced I'm missing something.
Any help would be appreciated.
