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 Nikon system 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 Nikon system compatibility table on the Nikon website.
