Viewfinder/viewing & focusing
The conventional \«ay of securing correct focus is to turn the
lens focusing ring until the image in the viewfinder appears
sharp. The K2 focusing screen that comes with the camera as
standard equipment has three focusing aids. When focusing
with the split image, turn the ring until the image in the two
halves becomes whole. With the microprism grid, turn the ring
until the shimmering image appears sharp. With the matte outer
fieid, turn the ring until the image appears sharp. The split-image
rangefinder works well for subjects with definite lines, contours
and boundaries. The microprism collar is for focusing on fast-
moving subjects or those with indistinct lines, while the matte
outer field is suitable for close-ups or when using lenses with a
maximum aperture smaller than f/4.5.
There’s another way of securing correct focus. Using the dis­
tance scaie ® on the lens, set the focusing ring in accordance
with the measured distance. Be sure to gauge the distance
between the subject and the film plane indicator-e-#.
Note: The FM2 viewfinder covers approx. 93% of the image area of the
actuai photograph so the actual picture comes out larger than the image
in the viewfinder. Note that the picture comes out trimmed down in the
case of mounted slides or service-size prints from negatives.
With AF Nikkor lenses: Set the lens' A-M ring or A-M switch
to "M."
