With Built-in TTL Metering
The Micro-Nikkor has a fully automatic dia-
phragm with settings from f/4 to f/32. The
Micro-Nikkor couples fully to the thru-the-
lens meter of any F/F2 Nikon Photomic or
other Nikon/Nikkormat cameras for full aper-
ture exposure measurement over the entire
range of aperture settings. Note that when
this lens is used with non-AI cameras,
con-
ventional "manual" maximum aperture in-
dexing is required.
When close-up attachments such as a PN ring
or bellows are used, the exposure measure-
ment method is shown in the table on the left.
When the lens is mounted in the reverse
posi-
tion,
the stop-down method should be used.
See the instruction manual supplied with your
camera or Photomic viewfinder for details.
Caution:
When the stop-down method is used at
small apertures, a finder eyecup should be attached
to the eyepiece to ensure complete exclusion of
stray light.
