DETERMINING EXPOSURE
With built-in TTL metering
The Micro-Nikkor 105mm f/2.8 has a fully auto-
matic diaphragm with settings from f/2.8 to f/32.
The lens couples fully to the through-the-lens meter
of any Nikon AI or F/F2 Photomic camera for full
aperture exposure measurement over the entire range
of aperture settings.
When close-up attachments such as a PN ring or
bellows are used, the exposure measurement method
is shown in the table at the right.
• When the lens is mounted in the reverse position,
the stop-down method should be used. (For details,
check your camera's instruction manual).
• When the stop-down method is used at small aper-
tures,
attach a finder eyecup to the eyepiece so no
stray light will enter.
