Looking at geared tripod heads it seems that the Arca Swiss Cube is the yardstick. There is a version of the Cube with gears for the panning motion as well as tilt/yaw link to article called the Cube GP (Geared Panning).
Now the Cube is out of my price range (and also is bigger and supports more weight than I need) so while looking at alternatives I came across Leofoto G2 which is a MUCH cheaper and lighter alternative to the cube but this lacks the geared panning.
Is there separate Geared Panning plates out there that I could buy? I have searched for such a product but my google fu is weak.
The intended use case is precision framing using a long macro lens (for example Sigma 100-300mm f4 with extension tubes) but I will mostly do other kinds of photography so I want a compact head and not one with large handles sticking out ruling out Benro GD3WH and similar heads.
