M37-K Mount Adapter

This adapter converts M37 thread mount lens to PENTAX K bayonet mount.
M37 thread mount lens was used for vintage Asahiflex camera.
You can enjoy these vintage lenses by the newest camera.

The adapter has a flange, but position of the lens mount is same as that of the camera mount.
(The flange distance was designed as 45.5 mm and the lens mount diameter was designed as 46 mm.)
In the past product 'M37-M42 Mount Adapter', if you attach into 'PENTAX Mount Adapter K', focus at infinity position will pass over infinity because Mount Adapter K is attached at the back of the camera mount surface.
This is a better way to use M37 lenses for your K mount camera.

*Note
First, printed adapter has joined by 'bar'. Cut the bar by nippers.
Clean up plastic powder before using: it remains in the screw part of the adapter.
By tolerance etc.,  you may feel tight when you attach the adapter to your lens or camera. Don't screw tight with your force. Tighten and loosen little by little, finally, you can attach!
Don't forget 'AT YOUR OWN RISK'
