If you want to finely adjust your backfocus even more precisely than with fine tuning rings, choose the Artesky precision adapter!
It allows you to adjust the distance within a range of 3 mm (the total thickness of the male / female adapter varies from 15 to 18 mm) and to lock it with 3 grub screws, each offset by 120°.
The internal thread allows a variation without bending, play or errors.
The precision tuning ring is available in T2, M48, M54 and M68 versions.
