The Panasonic Lumix DMC-GH4 Mirrorless Micro Four Thirds Digital Camera is
a true hybrid camera designed for both professional photo and video
use. It features a 16.05-megapixel Digital Live MOS sensor and a 4-CPU
Venus Engine, capable of capturing high-resolution JPEG and RAW stills,
as well as UHD 4K 3840x2160 30p/24p and cinematic DCI 4K 4096x2160 video
at 24p. Like its predecessor, the GH4 features a weather-sealed
magnesium alloy body, while offering increased resolution on both the
OLED monitor and electronic viewfinder. It also features built-in Wi-Fi
with NFC technology, in-camera creative controls, and a high-speed
49-point autofocus in both photo and video mode.
The GH4 delivers video quality surpassing many professional video
cameras. Video can be recorded in a variety of formats, from efficient
AVCHD and AVCHD Progressive, to 200 Mbps All-Intra and 100 Mbps IPB MOV
and MP4 formats. And because the GH4 is a global camera, the system
frequency can be switched between 59.94 Hz (23.98 Hz) and 50 Hz,
yielding a variety of recording options including 23.98p, 25p, 29.97p,
50p, and 59.94p. The system can also be switched to 24 Hz to capture
true 24p in HD and 4K resolutions.
Video and photos are recorded to SD/SDHC/SDXC memory cards. Video
recorded to SD cards is 4:2:0 8-bit. Real-time 4:2:2 8-bit and 4:2:2
10-bit video can also be sent to an external monitor or recorder with an
optional micro HDMI cable. Additional video features include focus
peaking, time code support, and cine-like gamma options. For unique
expressions, VBR (Variable Frame Rate), time lapse, and stop motion
animation videos can be recording internally without the need for
additional post-production processing. The GH4 comes with a rechargeable
lithium-ion battery pack, battery charger with AC cable, body cap, hot
shoe cover, USB cable, shoulder strap, and DVD with supplied software.
- 16.05 Megapixel Digital Live MOS Sensor and Venus Engine
- The
16.05-megapixel Digital Live MOS sensor delivers high-quality images
with high sensitivity and quick response times. The increased signal
speed readout helps to suppress the effects of rolling shutter. In
conjunction with the quad-core Venus Engine image processor, you'll
enjoy dramatically improved sensitivity (maximum ISO 25600), gradation
performance, resolution, and color reproduction.
- Micro Four Thirds Sensor and Lens Mount
- The
DMC-GH4's Micro Four Thirds sized sensor is large enough for shallow
depth of field and yet small enough to take advantage of lighter, more
compact lenses than a larger format camera would require. Plus, the
short flange focal distance of the Micro Four Thirds Lens Mount makes it
possible to add optional adapters (sold separately) to use a wide range
of lenses, including PL-mount cinema lenses.
- Dual OLED Displays - Monitor and Live View Finder
- High-speed,
organic LED displays are used for both the Live View Finder and the
rear monitor. The 3.0" monitor features a 1,036K-dot resolution, while
the LVF features a 2,359K-dot resolution. These displays feature 100%
coverage and a 10,000:1 contrast ratio. An Eye Sensor automatically
switches between the Live View-Finder and the rear monitor, for easy
shooting with both.
- Magnesium Alloy, Weather Sealed Body
- The
DMC-GH4 features a magnesium alloy full die cast front and rear frame. A
splash and dustproof design is achieved by tightly sealing the joints
and control components. To further meet the demands of professional use,
the shutter is rated for approximately 200,000 releases.
- Wi-Fi with NFC Technology
- The
DMC-GH4 integrates Wi-Fi connectivity with NFC, letting you use the
Panasonic Image App for remote photo and video shooting with compatible
smartphones or tablets. The app also lets you embed location data to an
image after shooting. If your mobile device isn't NFC compatible, you
can still connect to the camera by scanning a QR code displayed on the
GH4's monitor.
- 49-Area AF / Custom Multi AF
- The
newly developed AF system features 49 points, giving you more
flexibility when composing shots. The Custom Multi mode extends that
flexibility even more with the ability to freely select what blocks to
focus out of the 49 possible focusing areas.
- High-Speed Autofocus
- The
high-precision Contrast AF integrates DFD (Depth from Defocus)
technology to achieve AF speeds of approximately 0.07 sec in AFS mode.
This enables the camera to shoot bursts of 12 fps in AFS mode.
- Silent Mode
- The
Silent mode switches the shutter from mechanical to electronic and
turns off sounds, while suppressing the AD assist lamp and flash with
just a single setting. This is useful when capturing photos in
situations where noise and light from the camera would be a distraction
to performers or people around you.
- In-Camera RAW Data Development
- Shoot
RAW photos and process the images in-camera to create JPEG images,
instead of relying on post-processing. You can adjust the color space
setting (sRGB / AdobeRGB), white balance, noise reduction, sharpness,
and hue. Lumix's Photo Style, Intelligent D-Range Control, and
Intelligent Resolution can also be applied.
- Picture Profiles
- Choose
from a range of Photo Styles and Creative Control modes. Photo Styles
for stills or video include Standard, Vivid, Natural, Monochrome,
Scenery, Portrait, and Custom. Contrast, sharpness, noise reduction,
saturation, and hue parameters can be adjusted for each mode and even
set into the camera's memory.
- Professional 4K Video Recording
- The
DMC-GH4 brings the GH-line into the 4K age by offering both 16:9 UHD 4K
3840x2160 video at 23.98p, 24p or 29.97p, and 17:9 DCI (Digital Cinema
Initiatives) 4K 4096x2160 videos at 24p. 4K resolutions can be recorded
as MOV or MP4 files in high bitrate 100 Mbps IPB codec. When recording
at 100 Mbps, you will need an SDHC/SDXC memory card capable of handling
the transfer speed.
Please note: For
better quality, 4K recording modes use a 1:1 pixel map of the sensor.
This yields a slight crop of the sensor, resulting in approximately a
full-frame crop factor of approximately 2.3x when shooting DCI 4K
resolution.
- Selectable System Frequency
- The
DMC-GH4 is a true global camera, with system frequency switchable from
59.94 Hz (23.98 Hz) and 50 Hz. You can also select 24 Hz frequency for
true 24 fps cinematic video.
- VFR (Variable Frame Rate)
- The VFR mode enables Full HD video recording with slow/fast motion, depending on the video format and system frequency selected.
