Nikon Fisheye-NiKkor 16mm f/2.8 Manual De Instrucciones página 9

FOCUSING---------C
Due to its fully automatic diaphragm, the Fisheye-
Nikkorcan be focused with maximum image bright-
ness on the screen throughout the entire focusing
range. The Fisheye-Nikkor focuses from infinity
down to 1 foot (O.3m). In this way you can focus
on foreground subjects while throwing the back -
ground out of focus or move in close to the subject
without stopping down the lens.
To focus, look through the camera viewfinder and
turn the focusing ring until the image on the screen
appears needle-sharp.
Depth of field can be observed by simply pressing
the camera's depth-of-field preview button; or refer
to the table on page 24.
