I just had to find something stable for my new old Sinar F2. I finally relented and bought a Berlebach Ash wood tripod and one of their 3 way heads: 3D Super Spezial. The Spezial has a 100mm round mounting plate and no video grip that extends out. I love it. It has no QR, just a screw. It feels rock solid. They also offer a 2D version. And the normal 3D version with detachable, long video grip and a square non QR plate. 60+ x 80+ mm.
The base plate that mounts to the tripod is 89mm, I believe. It works with the 75mm, 15° leveler of my tripod. Just...
I had the combo out, yesterday and there was some wind and a few gusts (sunny weather, probably thermals). The camera didn't visibly move. For the exposures I still waited for a short lull and later it died down. At night the big storm that hit the northern half of Europe arrived here and is still somewhat going.
