M65x1 helicoid to M68x1 female thread adapter for Pentacon Six

• Front side - M65x1 female thread
• Rear side - M68x1 female thread
• Weight - 24 g

This adapter allows using focusing helicoids with M65x1 thread mount on Pentacon Six cameras with removed bayonet nut.

Such modification allows saving about 4.5 - 5.0 mm compared to regular M65 to P6 adapter, so you can use more lenses this way.

Made of anodized aluminium.
