Seamless Follow Focus gear ring
A high quality 3d printed standard 0.8 Mod pitch seamless lens gear to fit 55mm to 59mm diameter lenses.
Width: 10mm
Manufactured in tough but flexible TPU (thermo polyurethane).
Slide on compression fitting for easy installation and removal.
Allows unobstructed 360 degree rotation of lens barrel.
 
Choosing a ring size:
For a good fit, the lens ring size should be at least 0.5mm smaller than the diameter of the lens barrel.
Measure the diameter of the focus/zoom barrel on your lens. Subtract 0.5mm then and round down to the nearest whole millimetre.
TPU lens rings will stretch up to 2mm so a 75mm diameter lens ring for example will fit a lens barrel diameter of between 75.5mm and 77mm.
 
Custom designs available on request. 
Rings can be made extra small/large/narrow/wide and in a variety of different colours.
