M42x1 thread adapter for LOMO OKS8-35-1 lens optical block

This adapter allows mounting LOMO OKC8-35-1 optical block onto Chinese M42x1 focusing helicoid.

Full required setup consists of:

1. This adapter.
2. Chinese M42x1 focusing helicoid with 17-30mm extension range (we don’t sell them).
3. Our short M42x1 to MFT or M42 to Nikon-1 adapter (infinity-allowed M42 adapters will not work).

Such setup is quite weird as you can see on the pictures, but it does necessary job providing focusing from about 20 cm to infinity.

For sale in this listing is the M30x0.75 to M42x1 adapter only.
