Extension tube M48 / M63 variabel 20.5 - 31mm

Variable Extension for setting of exact focus distances

This Extension was developed for accurate setting of distances from cameras to correctors. Due to the stable design, even accessories of several kilograms weight can be held precisely.

The distance is continously variable and can be locked by a stable locking ring. The locking ring has a lateral lever which allows reliable clamping, but also easy loosening of the clamping even with gloves.
