The new camcorders use
Sony’s 1/3-inch 3 ClearVid CMOS Sensor™ system enhanced
by Exmor™ technology. With a 45-degree rotated pixel layout,
the 3 ClearVid CMOS Sensor system offers
sufficient pixel surface area while maintaining high resolution.
The Exmor technology features a unique column-parallel
analog-to-digital conversion technique and dual noise canceling,
resulting in high-quality digital signals with extremely low noise,
similar to the imaging technology used in the PMW-EX1 camera. The
two new technologies combine to allow the new camcorders to perform
significantly better in low-light environments with sensitivity of
1.5 lux. *
This imaging technology is complemented by Sony’s
Enhanced Imaging Processor™ (EIP) system to achieve high
resolution, high sensitivity, wide dynamic range, and excellent
color reproduction.
Users can attach different lenses for extra flexibility, and both
models have a universal standard 1/3-inch bayonet mount mechanism
for easier lens changes.
Each camcorder comes standard with a 12x high-quality,
multi-purpose Carl Zeiss lens for HD video, with a
Vario-Sonnar™ T* coating to reduce reflections. A specially
designed 8x wide-angle lens is also available as an option.
These new lenses give the camcorders the same functionality as
Sony’s popular fixed-lens camcorders like the HVR-Z1 and
HVR-V1, thanks to built-in features such as auto-focus, optical
stabilizer, and automatic back-focus adjustment. Using a
special adaptor, users can also attach the
α lens series designed for Sony’s consumer
digital SLR still cameras.
The camcorders offer 1080, 24p and 30p native progressive
recording. The 3 ClearVid CMOS Sensor system and EIP
technology create true 1080p images, which can then be recorded as
progressive signals by the HVR-Z7 and HVR-S270 camcorders in the
HDV format. The progressive HDV streams can be output from an
i.LINK® interface and used for progressive editing with
compatible NLE software.
The HVR-Z7 and HVR-S270 can switch between 1080p, 1080i in the HDV
format, DVCAM™, and DV recording, and both can down-convert
material from HD to SD, and output the video signals through its
i.LINK interface and other SD output connectors. The HVR-Z7 has an
HDMI output. The HVR-S270 is available with HD-SDI or SD-SDI
connectivity, and also supports embedded audio and timecode.
The HVR-Z7 and HVR-S270 use Sony’s XtraFine™ LCD and
XtraFine electronic viewfinder for high-resolution and
high-contrast images with remarkable color reproduction. The
HVR-S270 features a new LCD/EVF configuration named “Dual
Finder,” where the LCD located on the EVF enables multiple
styles of operation.
The new camcorders offer the option of hybrid recording when using
a supplied memory-recording unit, which attaches directly to the
back of the HVR-Z7 or the side of the HVR-S270 and eliminates the
need for cables. The unit automatically synchronizes with the
recording action of the camcorder and a special shoe connector
inputs and outputs an HDV/DV stream and supplies power to the
unit.
This unit captures the HDV1080i, DVCAM, or DV stream output from
the camcorder and can record HDV/DVCAM/DV files to a standard
CompactFlash® solid-state memory card, while users are
simultaneously recording to tape.
It will be compatible with Sony’s Professional 306x
CompactFlash card as well as standard CompactFlash cards (2GB
minimum capacity, 133x minimum speed). The recording times on an 8
and 16 GB CompactFlash card in HDV, DVCAM and DV format are
approximately 36 and 72 minutes**, respectively.
The HVR-Z7 can deliver more than 60 minutes of recording time on
miniDV videotapes, and approximate recording times of 63 minutes
with Sony’s DigitalMaster™ cassettes (PHDVM-63DM). The
HVR-S270 also accepts standard-size cassettes to provide more than
4.5 hours of continuous recording, with approximate recording times
of 4 hours, 36 minutes** on Sony PHDV-276DM
videotapes.R-
