Make the most of your existing collection of Pentax K-mount lenses with this Pentax K Lens to Nikon F-Mount Camera Lens Adapter from Vello. This durable adapter will allow you these lenses to be mounted to a Nikon F-mount camera. Precise construction makes it easy to attach an adapted lens to a camera body and keep it secure during use. Infinity focus is guaranteed, ensuring proper functionality when shooting at long distances. In order to achieve infinity focus, an optical glass element is used, which features a coating to minimize the chance for glare and reflections.

The adapter is made from a durable zinc alloy for long life. Although the lens will fit physically, autofocus, automatic diaphragm (AE metering), and other functions dependent on communication between camera body and lens will be disrupted by the lens adapter. Focus and exposure will need to be set manually, or metered in aperture priority (stop-down) mode.
