This professional adapter allows you to use Pentax lenses from the 35mm reflex (series with opening ring) on your Nikon reflex camera. Since the distance to the plane of the film is different in both frames, the device incorporates a correction lens. This allows you to focus on infinity without problems. The adapter increases the focal length as a 1.4x teleconverter. Manufactured with quality materials and excellent finish. There is usually a large decrease in contrast to full aperture and diffraction at high numbers of diaphragm closure due to the presence of this lens in the adapter.

Our adapters deliver infinity focus, manual aperture control, and a sturdy build for lasting quality.

Note:
This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted.
Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode.
If your lens does not have a manual aperture control ring, it will stop down to its smallest f/stop by default.
