Do not leave the viewfinder lens faced toward a strong
light source, such as sunlight.
A concentration of strong light, such as sunlight via the
lens may burn out the OLED panel or cause a fire.
About the OLED panel
The OLED panel fitted to this unit is manufactured with
high precision technology, giving a functioning pixel
ratio of at least 99.99%. Thus a very small proportion of
pixels may be “stuck”, either always off (black), always
on (red, green, or blue), or flashing. In addition, over a
long period of use, because of the physical characteristics
of the organic light-emitting diode, such “stuck” pixels
may appear spontaneously. These problems are not a
malfunction.
These phenomena have no effect on the camera’s output
signals.
Burn-in
Due to the characteristics of the material used in the
OLED panel, permanent burn-in or reduction in
brightness may occur.
These problems are not a malfunction.
When still images are displayed in the same position on
the screen continuously or repeatedly, permanent burn-in
may occur.
• Turn off the character and marker displays
Press the MENU switch to turn off the character
displays. To turn off the character or marker displays of
the connected equipment, operate the connected
equipment accordingly. For details, refer to the
operation manual of the connected equipment.
• Turn off the power when not in use
Turn off the power if the viewfinder is not to be used for
a prolonged period of time.

Do not subject the screen to strong
impact
Strong impact on the screen may damage it, such as
deformation of the internal structure or outer appearance.
Electrolytic capacitor
The life expectancy of the electrolytic capacitor is about
5 years under normal operating temperatures and normal
usage (8 hours per day; 25 days per month). If usage
exceeds the above normal usage frequency, the life
expectancy may be reduced correspondingly.
Operation and storage environment
Store the viewfinder in a level and air-conditioned place.
Avoid using or storing in the following places:
• Places that are extremely hot or cold
• Places with a high level of humidity
• Places with strong vibrations
• Places with strong magnetic fields
• Places that are exposed to direct sunlight for long hours
or near a heating device
Dew condensation
If the unit is suddenly taken from a cold to a warm
location, or if ambient temperature suddenly rises,
moisture may form on the outer surface of the unit and/or
inside of the unit. This is known as condensation. If
condensation occurs, turn off the unit and wait until the
condensation clears before operating the unit. Operating
the unit while condensation is present may damage the

Overview
The HDVF-EL30/HDVF-EL20 OLED Viewfinder is a
color viewfinder for use with a Sony high-definition color
camera.
This viewfinder has the following features.
Advantages of OLED panel technology
The OLED panel makes use of an organic material, which
emits light when an electric current is applied. Being selfemitting, the strength of luminescence can be controlled
by the amount of electric current. This brings about the
following three features:
Quick motion picture response:
The luminescent state of the OLED panel can be changed
instantaneously by changing the current flow in the
organic material. This enables a quick motion picture
response and production of images with minimal blurring
and ghosting. Furthermore, performance for shooting on
location is not influenced by changes in environmental
temperature.
High contrast and wide dynamic range:
The OLED panel does not emit light when black signal is
applied to the viewfinder, enabling a pure black screen to
be displayed. Furthermore, thanks to high peak brightness
the panel impressively displays brilliance and clarity of
various sparkling images, such as stars in a night sky
twinkling, night illuminations winking or glass glittering,
etc.
Rich color reproduction:
An OLED panel’s self-luminescence also allows for great
color reproduction across the entire spectrum in
practically any shade or brightness.
Disposal of the unit
Do not dispose of the unit with general waste.
Do not include the unit with household waste.
When you dispose of the unit, you must obey the law in
the relative area or country.
