M42x1 thread lens to OCT-19 camera mount adapter
Allows using M42 lenses on camera with OCT-19 mount.
This adapter allows you to use Zenit/Praktica M42 lenses on your Konvas-2M camera. Due to necessity to match flange focal distance, we had to protrude it inside the camera. This causes two problems:
1. This adapter will not fit Kinor-35.
2. Some M42 lenses will not fit it.
I have only three M42 lenses at the moment. All three fit the adapter and focus fine. Focus and aperture rings of Industar-50-2 and Helios-44-2 are accessible. On the Zenitar-M, aperture ring becomes unaccessible since it is located too close to the mount.
You should check dimensions of your lenses before purchase. Depth of the adapter is 19mm, inner diameter is 64mm. Make sure that your lens is slim enough in rear part to fit the adapter. If not, you still can use this adapter with your lens in reverse direction, but you'll be able to use the lens in macro mode only, and aligning of the optical axis may be tricky.
Also, this adapter has no stop ring for instant return diaphragm pin. You lens should have manual aperture mode switch.
