60mm Z-Drive Gear
This is a larger gear for the Z-Drive. It attaches to Z-Drives via three included screws. This allows the Z-Drive to engage with smaller diameter lenses than the original gear allows.
If you have an older version of the Z-Drive purchased before Dec 2015 and want to upgrade to the newer Z-Drive to allow for the larger gear, email email@example.com. There is a $75 charge for the upgrade.
