Mounting a Chronos 1.4 high-speed camera on a spinning lawnmower blade, and dropping things into the upside-down mower, recorded at 5900fps.
This started out as a project to see what the camera could take, it turns out it can take a lot of punishment! Spinning up to 1800RPM, with about 200G exerted continuously on the periphery of the camera, plus another 100-200G of shock when an impact occurs.
The biggest challenges were getting balance correct, and finding lenses that could take high G force without going out of focus. The wide-angle CS-mount zoom lenses distort under high G, causing the focus to shift. Some of the earlier shots are slightly blurry for this reason. In the end, I found a 2.8mm prime lens that handled the G force just fine.
