I dug out my SQ-AI to shoot snow last night and I did a test roll a few days ago to make sure things were still in tune. I noticed something odd- The 8s setting was not working at all. 4s worked fine as well as 1s and faster shutter speeds but for some reason 8s simply did not work. It looked as it if was shooting as fast as the camera goes (1/500).

Not really sure how to troubleshoot this any further. I mean, it looks like the 8s setting is simply broken.

Anyone else experience this?

As far as I know the batteries are fine.

FWIW there is a 16s and a B option. Naturally I could use bulb and time 8s but that's no fun.
