FOCUSING
^1
16
Thanks to its fully automatic diaphragm, the Micro-
Nikkor can be focused with maximum image bright-
ness on the screen throughout the entire focusing
range.
The depth of field is also minimized at maxi-
mum aperture, so that the image snaps in and out of
focus rapidly and distinctly.
To focus, turn the focusing ring until the image on
the focusing screen-appears sharp and crisp. Thanks
to the internal dual-helical system, the Micro-Nikkor
focuses continuously from infinity to 9-13/16 inches
(25cm) at a reproduction ratio of 1:2.
