Overview
The HDVF-EL75 HD Electronic Viewfinder is a 7.4-type
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 self-
emitting, 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.
Sony’s Super Top Emission OLED panel
The 7.4 type Quarter HD (960 × 540) OLED panel
features Sony’s Super Top Emission structure. Unlike the
conventional bottom emission structure of TFT, Sony’s
Super Top Emission OLED panel can reproduce a crisper
image due to high brightness.
Furthermore, a unique microcavity structure makes RGB
primary colors purer and deeper by utilizing light
resonance effects that magnify optimum light wave
lengths and diminish undesired light wave lengths.
Adding color filters allows even richer RGB
reproduction.
The panel’s 10-bit driver enables smooth gradation of
color shading.
Color space function
The matrix switching function brings to you broadcast
standard (ITU-R BT.709/EBU/SMPTE-C) color space
settings.
Setting the matrix to OFF reproduces images in the
original wide color space of OLED.
Proprietary feedback circuit
Automatic monitoring and feedback of emitted light and
color variation enable stable, long-term color
reproduction.
Focus Assist function
This viewfinder comes with original Focus Assist
function to support accurate focusing.
• Image magnification function
A portion of the image can be magnified vertically and
horizontally while displaying the image for composing
the picture. The magnified image retains full HD
resolution, as the input signal is not resized.
• Peaking Plus function
Edge enhancement can be performed on the object that
is specified using a color, area selected, or both.
To switch to preset adjustment settings
Brightness, contrast, peaking, and chroma levels can be
preset for selection through an assignable switch or a
menu operation.
Assignable switch
Two assignable switches each are provided on the left and
right handles for frequently used functions.
Tally indicators
The viewfinder comes with three tally indicators (red,
green, and yellow), which light up in response to tally
signals.
Check the connected camera to identify whether the use
of the yellow tally indicator is supported.
Waveform Monitor function
The input signal waveform can be basically displayed in
the sub display.
Superior operation
• New screen positioning mechanism
Use of a counterbalance mechanism to optimize weight
distribution of the panel and link arms allows screen
tilting and lifting at once with a light operational
feeling.
• Large handles equipped with assignable switches
Large handles each equipped with two assignable
