If you would like to customize a focus gear ring, please provide us with the following information:

  • WHAT IS Your LENS MODEL?  For example, Canon EF 70-200mm f/2.8L IS II USM.
  • WHAT IS THE DIAMETER OF THE FOCUS RING ON YOUR LENS?  How to measure the diameter:
  1. Cover the entire focus gear with a slip of paper and pull the two ends together tightly.
  2. Mark down where the two ends meet with a pen. Make sure to mark both ends.
  3. Spread out the paper slip and measure the distance between the two marks with a ruler in millimeters and then divide that number by 3.14. That number willl be the diameter of your lens. For example, if the two marks are 255mm apart, divide 255mm by 3.14 and you will have a diameter of 81.2mm. The focus ring size for your lens would be 81-83mm.
