Edit Reason: Unwanted smilie
I use Pentax cameras, and I've been watching this thread with interest, as whenever I tried a sequence with a short interval, it would start dropping frames after a while. I watched the video, but Pentax don't appear to show any buffer details, like on the Nikon in the video. So for a trial I fitted an auto-focus lens, and set the camera to continuous auto-focus. It was clear the camera was receiving the focus signal for every exposure, as the lens was trying to focus each time. I purchased a spare cable and set about carrying out the modification, it soon became apparent that with such small cables involved I wouldn't be able to make a reliable job of it. With a Pentax camera, the plug that fits the camera and the intervalometer is exactly the same, so I purchased a cable fitted with mono plugs. In a test, using a 1 second interval, it fired off 300 exposures without a single dropped frame. One effect of using a mono cable is it blanks out the rear screen, so it wouldn't be any good for a holy grail shoot, but I wouldn't be using such a short interval. So I will use the normal cable for a holy grail shoot, and the mono cable for everything else. I always use manual lenses for timelapse, for which Pentax cameras are well suited.
I don't know where the smilie came from.
