Ultimate Modular Series Stability Test shows it stands 5 Beaufort
Since a longer time I liked to proof the Wind Stability of the M Series.
I did a first test with 2 beaufort but wanted to go beyond this speed. So I took an industrial ventilator with 16800m3/h, 78cm diameter, 24kg which brought me up to 4. My knowledge form sailing and gliding ended in placing a conical tube in front of it and I managed to speed up to 34.7km/h which is in the middle range of 5 beaufort.
I tested with my D3 and 300mm/f2.8 with the air blowing directly to the camera lens combination on M2 RD8II placed on a Feisol 3372LV.
I took pictures of a ISO 12233 test chart.I used different shutter speeds: 2, 2.5, 4, 6, 8, 10 sec.
The pics were taken with ISO 200, f8.
Because M1 and M2 use the same rails I dare to say M1 would get the same results.

I will try to get to a higher speed if possible to see when M Series begins to trill.
I think this is a proof of a well and stable designed panohead series. Many thanks to Nick.
Another test I did with the laser with and without the camera lens combination: http://ge.tt/3LyRo7Q
