Studio Handy Camera
High Quality Images Achieved by a
Highly Developed DSP.
Advanced Digital Technology Allows
Compact, Lightweight Lenses to
Studio Production Needs.
3CCD with High Sensitivity, Low Noise and Low Smear
The 2/3 type 2.2 megapixel 3CCD enables the standard sensitivity
of F11 (2,000 lx/59.94 Hz) which is one of the highest sensitivity in
this range of cameras. A high S/N ratio of 60 dB (at 59.94 Hz)
produces high quality images with low noise and low smear.
Panasonic's single-channel transfer system and spatial-offset
processing technologies also improve signal modulation depth and
reduce moire.

With spatial-offset processing, green
samples are offset, allowing change in the
object to be more faithfully reproduced.
High-Performance
DSP Provides 16 bit A/D,
38 bit Processing
HD images are digitized with
74 MHz sampling and 16 bit A/D
conversion. Full 38 bit
processing within the DSP
produces highly detailed,
high quality images.
Multi Video Format
For HD, supporting 1080/59.94i, 1080/50i, 1080/23.98p, 25p and
1080/29.97p video format are supported as standard. In addition,
720/59.94p, 720/50p and 1080/23.98PsF video format can also be
supported when selected on CCU.
Chromatic Aberration Compensation (CAC)
This exclusive technology sets up a conversation between lens and
camera which allows for a highly sophisticated algorithm to be
deployed that will automatically compensate the registration error
that is caused mainly by lens chromatic aberration, and minimize
the circumjacent blur.

Film Rec Gamma and Scan Reverse Functions
Selectable gamma curves are included in the DSP circuit. The Film
Rec mode produces the kind of film tone that you get with
Panasonic VARICAM models. The Scan Reverse function is
mounted by standard functions that cancels the image inversion
that happens when using a HD lens adaptor or shooting with
special effects such as 3D rig.

Digital Extender (2x)
This function expands the image by 2x in the digital signal
processing circuit, allowing powerful shooting even with a
low-magnification lens. HD images retain their superior resolution
even with zooming, and — unlike when a lens extender is used —
brightness is not reduced.
Dynamic Range Stretch (DRS)
The DRS function automatically suppresses blocked shadows and
blown highlights. A gamma curve and knee slope are estimated to
match the contrast of each pixel, and applied in real time. When
dark, bright, and intermediate shades are all contained in the same
scene, this produces excellent gradation for each shade. The
images that result are enhanced by a visually wide dynamic range.

While suppressing washed out colors such as those when shooting garden greenery,
it also reduces blocked shadows in dark areas when recording people indoors.
Other Advanced Digital Functions
• 12-axis color correction, linear matrix, and other color
correction functions.
• Selectable EBU or NTSC preset matrix.
• A skin tone detail function with two
skin tone settings.
• A lens file function (for up to
32 files) to save flare and shading
values.
• Camera settings, such as VF
settings, can be saved on
an SD memory card. SD
memory cards can also
be used for firmware
upgrades.
• Various information,
including the color
temperature setting,
is displayed in the
viewfinder.
