User manual NIKON NIKKOR ED 1200MM F/11 IF

[. . . ] Other convenient features include a built-in telescopic lens hood, built-in tripod mounting collar, presettable focusing ring for rapid refocusing to a certain distance, and full aperture through-the-lens metering with Al-type Nikon and Nikkormat cameras*. The ED 1200mm f/11 IF has special insertion-type filter holders accepting either 39mm screw-in or gelatine filters. [. . . ] The filter holder will come free and can be lifted out of the lens. Unscrew the filter and replace it with the one you wish to use. Lock the filter holder back in place by reversing the above procedure. A special filter holder is provided with this lens which accepts gelatine filters. To fit the filter, release the catch, flip open the filter plates, insert the gelatine filter, close the plates and cut off the excess with a sharp knife. The filter holder can then be mounted in the usual way. Please note that due to a slight difference in thickness between gelatine and glass filters, some focus shift may occur when changing from one type of filter to the other; this discrepancy is easily corrected, however, by slightly shifting the focus setting. A filter must be mounted in the lens at all times.
