Focusing
Focusing with the FX-70 Quartz is done by using any
element of its convenient Freeway focusing system
consisting of a split image spot, a microprism collar and an
outer matte field.
<Horizontal Split image Spot> When using the split-image
spot to focus, turn the focusing ring until the top and bottom
halves of the image merge. If the image is out of focus, the two
halves
will not merge.
<Microprism Collar/Matte Field> To focus with the
microprism collar, turn the focusing ring until the glittering
effect disappears from the collar area, giving you a sharp,
clear image when in focus. To focus with the outer matte field,
turn the focusing ring until the image appears sharp and clear,
free of any foggy effect.
· When using long focal length lenses, or lenses with a relatively small
maximum aperture 04 or slower), or when performing close-up
photography at high magnification, the microprism collar and split image
spot may become dark, making focusing difficult. In this case, focus using
the outer matte field.
<Diopter Lenses> Special correction lenses are available for those who
find it difficult to focus with their eyeglasses on. There are 8 types
available: -5D (diopters), -4D, -3D, -2D, OD, + 1 D, + 2D, and + 3D.
Choose the one suited to your eyesight needs. These lenses should be used
with an accessory eyecup.
