Nikon AI Lens Adapter for Pentax K200D K110D K20D

With this lens adapter, you can mount Nikon AI lenses on the Pentax K-mount digital SLR camera systems. The adapter mount adds a large number of compatible lens to the Pentax K-mount system.

When using the adapter mount, please take note of the following issues:

1. Autofocus (AF) is not available;
2. Stop-down metering is used. Spot metering mode does not work properly.
3. Although it is possible to use the A (aperture-priority AE) mode in auto exposure, the aperture display is not available.
4. In the P (Program AE), or S (Shutter speed-priority AE) mode, the shutter releases, but the auto exposure control does not work.
5. The distance scale on the AI lens may not indicate the actual distance. Always use the viewfinder for focusing.
6. For recommended lenses, focal lengths and aperture (F-number) ranges, please refer to the K-mount system compatibility table on the Pentax website.
