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 m anual).

When the stop-down method is used at small aper­

tures, attach a finder eyecup to the eyepiece so no

stray light will enter.
