17. FOCUSING
Focusing is achieved with the Split-image, Microprism or Matte focusing
screen in the viewfinder. The viewfinder image is crucial for accurate
focusing of the lens, and therefore greatly influences image sharpness.
Different photographic applications often require different focusing screens.
The optimum type of focusing depends on the subject and the lens being
used. (Fig. 39, 40)
While looking through the viewfinder, focus by turning the focusing ring.
(Fig. 41)
Types of Focusing
A. Split-image The area inside the central circle is the split image. When both
images in the split-image area form a single clear image, the subject is in
focus. The split-image helps you focus quickly and easily on subjects with
clear lines or contours. (Fig. 42)
B. Micropasm The area inside the outer circle is the microprism. When the
image stops "flickering" and is sharp and clearly visible, the subject is in
focus. The microprism allows fast and precise focusing on subjects without
recognizable lines or contours. (Fig. 42)
C. Matte screen
The area outside the microprism is the matte screen. Focusing is done by sight and requires practice as the transition
from unsharp to sharp is gradual rather than abrupt. The matte screen helps you focus precisely with lenses of longer
focal lengths as well as in the macro range. (Fig. 42)
· When you use a small aperture (large number aperture setting) with a lens such as a zoom lens, half of the split
image becomes dark. In this case, use the matte screen to focus.
18. SHOOTING
1. Press the shutter button halfway. (Fig. 43)
· The LCD panel and viewfinder display operate.
· The shutter button can be pressed in two ways. If it is pressed halfway, the
LCD panel and the viewfinder display operate. If it is pressed fully, the shutter
is released.4www.butkus.org
· If the camera is not operated for about 10 seconds, the display inside the
