Features：
1. This lens mount adapter is suitable for Nikon F lens to PK camera.
2. Made of premium aluminum alloy and brass, adopting anodized aluminum construction.
3. Install, remove and operate lens smoothly.
4. There are no electrical contacts in the lens adapter ring. Exposure and focus has to be adjusted manually. Auto focus (AF) is not available.
5. This lens mount adapter has a built-in corrective lens, which makes the adapter allow focus to infinity.

Please note:
Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate correctly while using this adapter.

In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. You can shoot with manual mode or aperture priority mode.
