PDMOVIE Marking Disk Set for PD4-HT Controller for REMOTE AIR PRO 3 (2-Pack)

This Marking Disk Set two-pack from PDMOVIE is compatible with the PD4-HT Controller unit for the REMOTE AIR PRO 3 focus motor. Use each white plastic disk for creating custom focus marks used for pulling focus. The two disks allow you to pre-mark each disk to match the focus scale of a specific lens, so you can swap the disks when you change lenses or just have a clean spare ready to go when needed.
