Just took delivery of my very own M1L pano head with the RD16 rotator, Nadir adapter, camera plate and quick release clamp.
What a magnificent piece of photo equipment! It came pre assembled, but knocked down and stored in the protective case. I did not have any of the assembly problems I have read about here. It was basically slide the parts together, calibrate and start shooting.
The precision, the construction, the craftsmenship! WOW!
My last pano head purchase from Fanotech was the Nodal Ninja 3 (without the upper rotator click stops).
