Proving that they can push the GH-series even farther into
the video realm, the Panasonic Lumix GH5S is a mirrorless Micro Four
Thirds camera optimized for movie recording and low-light performance.
Revolving around a 10.28MP Digital Live MOS sensor, DCI and UHD 4K video
recording is possible at up to 60p and the large individual pixel size also
affords impressive low-light performance to an extended ISO 204800, along with
Dual Native ISO technology at ISO 400 and ISO 2500. Coupled with an updated
Venus Engine, the sensor and processor combination also enables faster readout
speeds along with 1.3x less rolling shutter distortion compared to previous
GH-series cameras. Internal DCI 4K30p recording is available with 4:2:2 10-bit
sampling and a full-size HDMI A connector can be used to simultaneously output
to an optional external monitor or recorder. The sensor's extended sensitivity
range has also been used to promote working with V-Log L and Hybrid Log Gamma
HDR modes for effectively increasing your dynamic range and affording more
flexibility when color grading during post-production. Beyond its video prowess, the GH5S is no slouch when it comes to stills
shooting, either. The sensor and Venus Engine combination enable recording
14-bit raw files with a top continuous shooting rate of 12 fps with single-shot
AF, or up to 8 fps with continuous autofocus. Borrowing from the video side, 4K
PHOTO modes are also available for shooting 8MP stills at up to 60 fps.
Benefitting stills, the Depth-From-Defocus AF system works quickly and
accurately using 225 dedicated AF areas, and is sensitive to -5 EV luminance
for working in extreme low-light conditions.
Beyond imaging specs, the GH5S retains its professional build quality the
GH-series is known for. The magnesium alloy body is fully weather-sealed for
working in inclement conditions, and physical controls have been enhanced for
easier tactile control. A large 3.68m-dot OLED electronic viewfinder is
featured, for high-resolution eye-level monitoring, as well as a rear 3.2"
1.62m-dot LCD touchscreen with free-angle movement to suit working from high
and low angles. Dual UHS-II SD memory card slots are available for flexible
file recording and built-in Wi-Fi with NFC and Bluetooth wireless connectivity
enable seamless image sharing and remote camera control from a mobile device. Engineered specifically for low-light
shooting and high-resolution video recording, a 10.28MP Digital Live MOS sensor
is featured, along with an optimized Venus Engine for clean color detail and
texture along with fast readout speeds. Using Multipixel Luminance Generation
and Intelligent Detail Processing, it will maximize sharpness and detail as
well as accuracy in a variety of lighting conditions. The sensor features a multi aspect ratio design, which enables the use of 4:3,
17:9, 16:9, and 3:2 ratios for shooting stills, recording DCI and UHD 4K, and
for working in Anamorphic mode. This unique design allows you to maintain a
lens's native angle of view despite changing the image format. Additionally,
the sensor and processor combination avails high readout speeds and suppresses
rolling shutter distortion by approximately 1.3x compared to the GH5 when
recording video or working with the electronic shutter. The sensor's deliberately low-resolution
design, and subsequently larger pixel size, also optimizes it for low-light
performance and enables recording a greater dynamic range. Borrowing from
Panasonic's broadcast line of video cameras, Dual Native ISO technology is used
that sets ISO 400 and ISO 2500 as base sensitivities for low noise levels. The
overall native sensitivity range runs from ISO 160-51200, and can be extended
to ISO 80-204800.
Beyond just a video camera, the GH5S is also adept at
recording stills. Using the unique sensor architecture, the low-light
capabilities and fast readout speeds make it ideal for working in difficult
lighting conditions and for photographing fast-moving subjects. For 12-bit raw
shooting, and when working with AF-S, continuous shooting up to 12 fps is
possible, along with a top 8 fps shooting rate with AF-C. For greater color
information, a 14-bit raw recording setting can also be used, and 11 fps and 7 fps
continuous shooting rates are available. For accelerated autofocus performance, and Advanced DFD (Depth-From-Defocus)
technology is employed to quickly calculate the distance to subjects and adjust
the focusing position in as little as 0.05 seconds. This contrast-detection
type focus method benefits both still and video recording modes, as well as
subject tracking applications where subject color, size, and motion vectors are
used to intelligently lock-onto the moving subjects and ensure precise focus.
The sensitivity and speed can be adjusted to further improve performance with
certain subjects. It also features 225 AF areas which provide excellent control
over where the camera will focus. Additionally, supporting working in low-light
conditions, a Starlight AF feature enables accurate AF performance down to -5
EV.
