I need to mount something similar - 300mm f2.8 lens on a FS7, what tripod bracket/mount did you use
so the 300mm tripod and FS7 can be on the same tripod plane?
I use a metal plate that is thin but strong. Primitive but effective.
Tripod is old Manfrotto with 100mm bowl. Don't expect smooth panning and tilting. Touching the on/off switch makes the whole lot shaking with this lens.
Camera Lens and tripod weighting 16 kilo (that is a lot of pounds).
