Focusing Screen
To handle a variety of photographic situations, the
FG-20 comes equipped with the Type K clear-matte
focusing screen, consisting of a split-image range-
finder
and microprism collar in the center of an overall
matte field.
While looking through the viewfinder, turn the focus-
ing ring ® of the lens until the subject looks clear. For
precise pinpOint focusing
on subjects with distinct
contours, use the central split-image rangefinder;
turn the focusing ring until the split image becomes
whole
(A). For rapid focusing and for subjects with
indistinct outlines, use the microprism collar; turn the
focusing
ring until the shimmering image becomes
24
sharp (8). In close-up or macrophotography, or when
using telephoto lenses with maximum apertures of
fl4.5 or smaller, the split-image rangefinder and
microprism collar are likely to darken. Therefore, use
the matte portion of the screen; turn the focusing ring
until the image looks sharp (e). The Matte field can
also
be used for focusing when shooting fast-moving
subjects.
- Because the FG -2 0's finder coverage is approx. 92%; the
actual image size
of your negatives will be slightly larger
than the image seen
in the viewfinder.
