Nikon AI Micro-NIKKOR 105mm f-4 - Manual (Page 10)

Recommended Focusing Screens
Nineteen different interchangeable focusing
screens are available for F and F2 Nikon
cameras to suit any type of lens or picture­
taking situation. Those which are recommend­
ed for use with this Micro-Nikkor 105mmf/4
lens are listed below.
®= Excellent focusing
®= Acceptable focusing
The image is brilliant from edge to edge, but the
center
area (range-finder, microprism or cross­
hair) is dim. Focus on the surrounding matte
area.
0= Acceptable focusing
Slight vignetting (or moire phenomenon, in the
case of the microprism) affects the screen image.
The image on the film, however, shows no trace
of this.
□ = Not usable
B= With these lens-screen combinations the view­
finder can be used only for focusing; exposure
measurement is not possible.
