[] EXPOSURE MEASUREMENT
Full-aperture measurement
The Photomic-T Finder is so ingeniously designed that, so for as the lens is coupled to
the Finder with the prong, the exposure can be determined with the aperture of the lens
fully open, no consideration being required as to the pre-selected aperture, to take
advantage of using the "Auto" lens, which permits getting view of the brightest nnder
image in focusing and composing.
Stap-down measurement
When a lens which is not provided with the coupling prong or when the coupling is
prevented by any intermediate attachment between the lens and the camera, the ex-
pcsure setting should be made with the operture of the lens stopped down to the
aperture actually being used Isee p. 191.

[] ORDER OF USING THE FINDER
The use of the Finder proceeds in the following order :
1) Set the film speed (ASAl to the max. aperture of the lens (see p. 10 1.
2) Push side button on the Finder to switch on the meter (see p. 11 I.
31 Look in Finder eyepiece to focus and compose the picture.
41 Set pointer needle inside the viewfinder or outside the Finder, by revo lv in g
shutter speed
selector on the top and/or aperture ring of the lens.

SETTING FILM SPEED TO THE MAX. LENS APERTURE
Be sure that the speed (ASA) of the film being used is _set to
the max. aperture of the lens. If it is not, turn the DIm speed
(ASA) dial
on the top of the shutter speed selector, using two
pins, so that the film speed (ASA) lines up with the max. F.
number of the lens engraved on the edge. For example, the
ASA 100
is set to the max . aperture F/ 1.4 as shown in the top
figure, and to F/ 2.8 in the bottom figure.
The intermediate dots in the film speed scale and in the max.
aperture scale correspond to the F·number
