Technical data

When the camera lens is focused on a certain objects in the foreground
and background will appear acceptably sharp in the picture. The range
over which the foreground and background objects are reproduced
acceptably sharp is called the depth of field. The photos on this page
were taken with the lens focused of the subject at the identical distance.
At F1.4, objects in the foreground and background appear blurred but, at
F16, they are reproduced sharp and clear. These photos illustrate that the
depth of field increases as you stop down the lens.
· The depth of field can be determined either visually by pushing in the
depth-of-field preview button or by reading off the depth-of-field scale
on the lens barrel. When using the scale, secure focus and read off the
range indicated by the identical figures on both sides of the index
corresponding to the f-stop in use.
· The depth of field is more extensive (1 ) as you stop down the lens, (2)
as you focus on a more distant subject, and (3) in the background rather
than in the foreground.
PRECAUTIONS
· Do not leave your camera in the trunk or g love compartment of your car or expose it to excessive heat. The battery
as well as the camera mechanism may become adversely affected by the heat, sometimes making it impossible to
obtain correct exposure.
When exposed accidentally to excessive heat, leave the camera to cool to normal ambient temperature.
· The most common causes of malfunction are exposure to humidity, salty sea breeze and subjecting the camera to
knocks and jolts. To obtain faithful service, take good care of your camera and avoid rough handling.
· To clean the surfaces of the focusing screen, deflection mirror and lens, always use a blower brush. Do not touch
