Do you have any pictures on how the springs attach to the blades? My camera fell from a tripod while setting up to make a star movie, the impact jogged everything loose. Thank you.

When I removed the cover, one of the springs came off. It’s a very tiny thing and you’ll need to use a tweezers to carefully hook it back to the moving blade and the fixed point. This serves as a caution to be very smooth when you remove that cover so as not to jar things. It’s the cover that actually holds all the blades in place so that’s one reason to be careful.

As mentioned: note that the mark 2 is evidently different than the original g9x (or perhaps a change was made in production at some time)
