A beautiful Nikon F2 without an finder will reveal the interior. The focusing screen are interchangeable type. The changing screen operates differently from Nikon F3 or F4, to drop out or insert the screen, press the finder release button at the back of the camera.

Nineteen different focusing screens are available for the Nikon F2-5 Photomic to match exactly any focal-length lens or picture-taking situation. The Type A Focusing Screen comes with the camera as standard equipment and any of the screens may be used with any of the finders available for the camera.

To change the focusing screen, first remove the finder as described earlier. Then turn the camera body upside down and press the finder-release button a second time. The screen will drop into your hand.

To attach a screen, place it in position with the flat side facing down and the Nikon mark pointing towards the front of the camera. Press the finder-release button and the screen will drop into place.

Caution: When changing a focusing screen, be careful not to touch the surfaces with the fingers as this will result in greasy marks. When removing the screen, it is advisable to place a clean, dry cloth over the palm of the hand for the screen to drop onto.
