When something is missing, the collector's value is substantially reduced. The pic on the right shows the bayonet lugs on the lens barrel and its bayonet lens shade. The lens cap is also bayonet. Below is the separate finder. Although the chrome Nikon mount is rarer, the black version commands slightly higher prices due to collector preference.
Bargains await the sharp eyed.
An interesting and unusual part of the design in Nikon mount is focusing is only possible using the focusing wheel on the top right front of the camera. It has NO external lens barrel focusing helical. My only complaint is the rather squinty view viewfinder. If you should be lucky enough to have one, I suggest trying the much better black Canon 25 finder or the current Leitz 24 finder. Copyright 1998 CameraQuest.
