Fotodiox Pro Aperture control adapter for Pentax-K lens to Nikon

This professional adapter allows you to use Pentax 35mm reflex lenses (series with or without 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.

Even so, there are many high-quality Pentax-K lenses that deserve to be used with Nikon reflex cameras.
