Negative Supply 雙軸熱靴氣泡水平儀

I’ve been using this to level my camera before each film scan, and the two-axis bubble makes it dead simple to get both planes squared up. It clicks into the hot shoe snugly, no wobble, and once it’s set I don’t have to fiddle again. One less variable in the scan workflow, which is worth it.

The two-axis bubble levels are perfectly visible even in dim light, which is key for my scanning setup. Snapped right into the hot shoe and felt solid, no wobble at all.

Leveling my camera for film scans used to take forever, but this two-axis bubble level slides right into the hot shoe and gets me square in seconds. It's compact enough that I forget it's on there until I need it.
