On the monitor, viewfinder, and lens
The monitor and viewfinder are manufactured using extremely high-precision technology
so over 99.99 % of the pixels are operational for effective use. However, there may be
some tiny black points and/or bright points (white, red, blue or green in color) that
consistently appear on the monitor and the viewfinder. These points are normal in the
manufacturing process and do not affect the images in any way.
Exposing the monitor or lens to direct sunlight for long periods may cause a malfunction.
Exercise caution when placing the product near a window or outdoors.
Do not press against the monitor. The monitor may be discolored and that may cause a
malfunction.
Images may trail across on the monitor in a cold location. This is not a malfunction.
If the monitor has drops of water or other liquids on it, wipe it with a soft cloth. If the
monitor stays wet, the surface of the monitor may change or deteriorate. This may cause
a malfunction.
When the battery pack is discharged, the product may shut off while the lens is still
extended. Insert a charged battery pack, then turn the product on again.
Make sure not to bump the lens or subject it to force.
Do not hold the camera by the monitor or viewfinder.
When the lens is in operation, be careful not to catch your fingers or any other objects in
the lens.
When pushing down the viewfinder, be careful not to catch your fingers in the viewfinder.
Do not force down the viewfinder when the eye piece is pulled out.
If water, sand, or dust adheres to the viewfinder, it may cause a malfunction.
Do not expose the camera to sunlight or shoot sunward for a long time. The internal
mechanism may be damaged.
Do not use the camera in areas where strong radio waves or radiation is being emitted.
Recording and playback may not function correctly.
Shooting with the viewfinder
When looking through the viewfinder, you may experience symptoms such as eye
soreness, fatigue, or nausea similar to car-sickness. We recommend that you take
periodic breaks when shooting with the viewfinder. Determine the necessary length and
frequency of breaks on your own, as these will vary from individual to individual. If
unpleasant symptoms occur, stop using the viewfinder until they resolve, and consult your
doctor if necessary.
Notes on the flash
Do not cover the flash with your fingers.
