Had a major error and the sequence stopped early. See error at the end of the log. Though this might have to do that I was saving RAW files by accident and the 16g card ran out of memory,
The error occurred because the camera stopped being ready to shoot within 2 seconds after a half-press. Once it got into that mode, it appears to have become stuck in that mode. I don't see anything in the log that might have caused that - the scene illumination had not shifted much.
However, the fact that you were saving RAW suggests a possible issue with processor / SD card write overloading.
Did another test befor and after sunset with filter factor set to medium. Lots of flickering and the change in speed.
One note, I set this for 3000 images and it stopped before that. I wasn't home so don't know if there was an error message. The camera was powered off and the lens was still extended. Hit the power to turn it back on then off again to retract the lens.
No lockup reported in the log like the one we saw in series 7. The same time sequence thing is happening though :
The write speed to the SD card slows down after a while, and then seems to release and the script run at a 2 second interval to catch up.
Focus still bounces around with this series, and the ND filter goes in & out. I'll look at the exposure variations next - I may want to see some of the original images if you still have them.
One thing we could also try is to isolate the timing glitches is a simplified intervalometer script that just shoots every 4 seconds in AUTO mode and that also logs to the SD card.
