Minolta X-700 - Manual (Page 18)

The X-700 uses standard 35mm
cartridge f i l m . If you are not al-
ready familiar with the many types
available, you may want to experi-
ment to find one or more that give
pleasing results for subjects you like
to photograph or for special situa-
tions.
The ISO f i l m speed (incorporat-
ing ASA and DIN numbers) indi-
cates the film's sensitivity to light.
The first part of the ISO number
(equivalent to ASA number) is
marked on the X-700's film-speed
ring. Each time this number doubles
(e.g., f r o m 25 to 5 0 , 50 to 100),
the required exposure is halved.
Such a change is called one " s t o p " .
Though selecting a high-speed
f i l m will allow you to take pictures
when there is less light, such films
in general may produce a grainier
image.

Setting f i l m speed
Lift up on the film-speed ring
and turn it until the proper ASA
number appears centered in the
film-speed window and locks in
that position when the ring is re-
leased. Marks between numbered
graduations indicate speeds shown
in the table at right.
