Benro FS20PRO has me utterly amazed and I don’t even know where to begin! At less than $85 it supports the Z400f4.5 with Z 9 attached and it works and feels like a fluid head but isn’t; weighting only half a pound and not being just ball nor rational head it performs perfectly! Benro Tortoise tripod and I are an incredible combination, and I use it everywhere. How exactly does it do all this? Honestly, I have no idea; all I know is it works beautifully and has what appears to be basic panning functions with locks that feel smooth as fluid panning functions. Locks for limited ball movement and full tilt movement make the movement of your camera platform seem as fluid and tensioned as a fluid head – yet cost less than $85 and weigh less than half a pound! I found a fantastically simple, elegant, solid head in this camera; its video handle folds down for storage containing an allen key and its mounting platform accepts Swiss Grove plates; both can rotate fully 360 degrees as does its panning base – perfect! My go-to solution! Absolutely breathtaking design.
