This was long time ago, FW 2.59b4,
first 6900 mm, then 690 mm and walking, after 6900 mm 690 mm feels vide :)

Hello Garug,
focal distance 6900mm (35mm) --> FOV = 0,23º
Probably a stabilization accuracy of about 50µrad
Very interesting test!
What lens and what camera did you use?

GH4 4k i.e 2.3 crop, very old canon FD 300 mm lens. The 6900 mm was 10X in camera with external recorder.
See the 10. Big lens on small gimbal

This is non encoder gimbal, but it should not affect the accuracy.
It was all handheld. The new IMU should be even more accurate.
Note, some of the vibrations are actually air.
