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.

however, shows no trace
of this.

Reproduction Ratio
The reproduction ratio is the numerical expres-
sion of the relationship between the image size
(to be recorded on the film) and the actual size
of the subject. For example, if the image on
the focusing screen is one-fifth the actual size
of the subject, the reproduction ratio is said to
be 1:5, and is indicated on the reproduction
ratio scale of the Micro-Nikkor 105mm f/4 by
the number "5'!
