In terms of functionality, the Panasonic Lumix GH4 Mirrorless Camera is a genuine hybrid camera that can be used for both professional photography and videography. It is equipped with a 16.05-megapixel Digital Live MOS sensor and a 4-CPU Venus Engine, which allows it to capture high-resolution JPEG and RAW still images as well as UHD 4K 3840×2160 30p/24p video and cinematic DCI 4K 4096×2160 footage at 24 frames per second.
While maintaining the weather-resistant magnesium alloy shell of its predecessor, the GH4 has a higher resolution on both the OLED panel and electronic viewfinder, as well as improved autofocus performance. Aside from that, it comes with integrated Wi-Fi and NFC technology, as well as in-camera creative options and a fast 49-point focusing system that works in both photo and video modes.
The GH4 produces video quality that is superior to that of many professional video cameras. Video may be recorded in a range of formats, ranging from efficient AVCHD and AVCHD Progressive to 200 Mbps All-Intra and 100 Mbps IPB MOV and MP4 formats, as well as 200 Mbps All-Intra and 100 Mbps IPB MOV and MP4 formats.
In addition, because the GH4 is a worldwide camera, the system frequency may be altered between 59.94 Hz (23.98 Hz) and 50 Hz, providing a range of recording possibilities such as 23.98p, 25p, 29.97p, 50p, and 59.94p. The GH4 also has a built-in flash that can be used to capture images in low light. When the system is set to 24 Hz, it is capable of capturing real 24p in both HD and 4K resolutions.
Memory cards such as SD, SDHC, and SDXC are used to record video and photographs. SDHC/SDXC UHS-I Speed Class 3 (U3) cards are supported and recommended for high-bit-rate formats with transfer rates of 100 Mbps and 200 Mbps.
Video recorded to SD cards is in the 4:2:0 color space and is 8-bit. With the optional micro HDMI connection, real-time 4:2:2 8-bit and 4:2:2 10-bit video may be delivered to an external display or recorder in addition to the internal monitor.
Additional video capabilities include focus peaking, timecode compatibility, and gamma choices that are similar to those found in the film. In order to get distinctive emotions, VBR (Variable Frame Rate), time-lapse, and stop motion animation movies may be recorded internally, eliminating the need for further post-production processing after the fact.
This kit includes a lithium-ion battery pack with a rechargeable charger and AC cable, a body cap with a hot shoe cover and USB cable, a strap for the camera’s shoulder strap, and a DVD with the included software.
The Venus Engine and a 16.05 Megapixel Digital Live MOS Sensor are used in conjunction.
The 16.05-megapixel Digital Live MOS sensor captures high-quality photos while also providing great sensitivity and rapid reaction times.
As a result of the faster signal readout, the effects of the rolling shutter are reduced to some extent. When used in conjunction with the quad-core Venus Engine image processor, you’ll notice a significant improvement in sensitivity (up to ISO 25600), gradation performance, resolution, and color rendition.
The Micro Four Thirds System and Lens Mount are also available.
The 4/3″ type sensor on the DMC-GH4 is large enough to allow for shallow depth of field while being tiny enough to allow for the use of lighter, more compact lenses than would be required by a larger format camera.
Additionally, because of the small flange focal distance of the Micro Four Thirds Lens Mount, it is possible to utilize a broad range of lenses, including PL-mount cinema lenses, by using extra adapters (which are offered separately).
Dual OLED displays – one for the monitor and one for the Live View Finder
Both the Live View Finder and the back monitor are equipped with organic LED displays that are extremely fast. The 3.0″ monitor has a 1,036K-dot resolution and a touchscreen interface for easy operation, whilst the LVF has a 2,359K-dot resolution and a traditional keyboard and mouse.
These displays have a 100 percent coverage area and a 10,000:1 contrast ratio, among other features. With an Eye Sensor, the camera automatically shifts between the Live View Finder and the back display, allowing you to easily shoot with both at the same time.
A magnesium alloy body with a weather-resistant finish is used.
The DMC-GH4 is built around a magnesium alloy front and rear frame that has been fully die-cast. The design is splash and dustproof due to the tight sealing of the joints and control components used in the construction. The shutter is rated for roughly 200,000 releases, which is more than enough to satisfy the rigors of professional use.
Wi-Fi with Near Field Communication (NFC) technology
Incorporating both Wi-Fi and NFC capabilities, the Panasonic DMC-GH4 enables remote picture and video shooting with compatible smartphones or tablets via the Panasonic Image App, which is available for free download from the Panasonic website. After you’ve taken a picture, you may use the app to incorporate location data into it. You can still connect to the camera even if your mobile device isn’t NFC-enabled by scanning a QR code that is shown on the GH4’s LCD panel.
Custom Multi-Area AF / 49-Area AF
The newly designed AF system has 49 points, which gives you greater choice when it comes to arranging your photographs. Custom Multi mode increases that versatility even further by allowing you to freely choose which blocks to concentrate from among the 49 different focusing zones.
Autofocus with a fast response time
DFD (Depth from Defocus) technology is used in conjunction with the high-precision Contrast AF to provide AF speeds of roughly 0.07 seconds in AFS mode. In AFS mode, this enables the camera to capture bursts of 12 frames per second.
Silent Mode is activated.
With a single adjustment, the Silent mode converts the shutter from mechanical to electronic operation and cuts off all noises, while also suppressing the AD aid lamp and flash. This is beneficial for taking images in settings where the camera’s noise and light might be a distraction to the performers or other persons in the vicinity of the photographer.
Development of RAW Data Right Out of the Camera
In lieu of post-processing, shoot RAW shots and process the images in-camera to make JPEG images instead of relying on the computer. There are options for changing the color scheme (sRGB vs. AdobeRGB), the white balance, noise reduction, sharpness, and the hue. It is also possible to use Lumix’s Photo Style, Intelligent D-Range Control, and Intelligent Resolution features.
Picture Profiles are a great way to get to know someone.
A variety of Photo Styles and Creative Control settings are available. Standard, Vivid, Natural, Monochrome, Scenery, Portrait, and Custom are some of the photo styles available for stills or video. It is possible to alter and save the settings for each mode in the camera’s memory. These parameters include contrast, sharpness, noise reduction, saturation, and hue.
4K Video Recording on a Professional Level
DMC-GH4 moves the GH-line into the 4K era by providing 16:9 UHD 4K 3840×2160 video at 23.98p, 24p, or 29.97p as well as 17:9 DCI (Digital Cinema Initiatives) 4K 4096×2160 video at 24p. The DMC-GH4 is available in black or white.
Recordings in 4K quality may be made as MOV or MP4 files with a high bitrate of 100 Mbps using the IPB codec. An SDHC/SDXC memory card capable of managing the transfer speed required while recording at 100 Mbps is required.
Please keep in mind that 4K recording modes make use of a 1:1 pixel map of the sensor, which results in higher quality.
When shooting at DCI 4K resolution, this results in a modest crop of the sensor, resulting in an approximate full-frame crop factor of around 2.3x when shooting in RAW.
System Frequency that can be selected
In addition to being a real global camera, the DMC-GH4 has a system frequency switchable between 59.94 Hz (23.99 Hz) and 50 Hz. You can also choose a frequency of 24 Hz for actual 24 frames per second cinematic footage.
VFR is an abbreviation for Very High Frequency (Variable Frame Rate).
- The VFR mode allows for the recording of Full HD video in either slow or rapid motion, depending on the video format and system frequency that is set.
- 59.94 Hz MOV/FHD/100 Mbps/29.97p, MP4(LPCM)/FHD/100 Mbps/29.97p: 2 frames per second, 15 frames per second, 26 frames per second, 28 frames per second, 30 frames per second, 32 frames per second, 34 frames per second, 45 frames per second, 60 frames per second, 75 frames per second, 90 frames per second, 96 frames per second

Video Recording Formats That Are Versatile
Select the video format that is most appropriate for each job. The DMC-GH4 is capable of recording video at very high bitrates of up to 200 Mbps (All-Intra) or 100 Mbps (Internal) (IPB). MOV, MP4, AVCHD Progressive, and AVCHD at a range of frame rates are among the formats that are available.
High-quality LPCM (Linear Pulse Code Modulation) sound may be captured in MP4 and MOV video formats. All internally recorded video codecs employ 4:2:0 color sampling and an 8-bit color depth, which is standard across the industry.
With HDMI, you can get real-time 4:2:2 output.
The mini HDMI output allows you to stream 4:2:2 8-bit or 4:2:2 10-bit video in real time to external displays or recorders. A micro HDMI cable, which is optional, is required. A video recording on the SDHX/SDXC memory card in the camera is impossible when the camera is producing a 4:2:2 10-bit signal through HDMI.
Peaking Your Concentration
The GH4 has a Focus Peaking function, which displays the peak of focus in MF and AF+MF modes to make focusing more convenient. While observing the topic in live view, users may witness the peaking of focus as it occurs.
In addition to being able to adjust the brightness to HIGH, LOW, or OFF, it can also be altered to blue, white, or orange to match the color of the shooting scene when in live view mode. Focus peaking is also accessible while shooting photos or videos remotely using a smartphone or tablet through Wi-Fi when using a smartphone or tablet.
Adjustment of the Luminance Level
As an alternative to the conventional brightness levels of 16-235 and 16-255, the Panasonic DMC-GH4 additionally provides luminance levels of 0-255 and 0-255.
Additional Video Characteristics
Synchronization of numerous devices using timecode that complies with SMPTE standards
Color bars serve as a reference point for adjusting color or brightness.
1 kHz test tone Is a reference point for adjusting sound or loudness.
The center marker serves as a guideline for video composition.
Synchro scan is a technique for suppressing flicker on computer displays or fluorescent lighting.
Cine-like gamma – The gammas “CINELIKE D” and “CINELIKE V” generate tones that are similar to those seen in movies.

Zebra Display lines on overexposed areas to create a pattern.
Professional Unit for 4K Video Interface (Optional)
The optional DMW-YAGH Interface Unit is designed for professional video processes and may be purchased separately. The Interface Unit is attached to the bottom of the camera and offers two XLR input terminals for line or condenser microphones, each with its own volume control and an audio level display monitor. The Interface Unit may be purchased separately.
As well as four simultaneous 1080p streams up to 30 frames per second, it has four 3G-SDI capable BNC connectors as well as two HD-SDI capable BNC connectors. It supports quad-link SDI 4K video with timecode in 4:2:2 10-bit, dual-link 4:2:2 10-bit 1080p up to 60 frames per second, and four simultaneous 1080p streams up to 30 frames per second. The device receives power via a 4-pin XLR input with a voltage of 12 VDC.
Please keep in mind that while utilizing the DMC-4:2:2 GH4’s 10-bit output, it is not feasible to record video on both an SDHC and SDXC memory card at the same time.
Photo Modes in 4K Resolution
In addition to the 4K video recording capabilities, a trio of still shooting modes are available for capturing continuous 8MP stills at 30 frames per second shooting rate. These are as follows:
- The 4K Burst mode, which works similarly to video recording, will allow you to continually record 8MP photos at 30 frames per second for up to 29 minutes and 59 seconds, making it perfect for situations when you need to capture the greatest moment possible at a rapid frame rate.
Pre-Burst in 4K: This mode is useful for situations where you are unsure of when to click the shutter button. It will record 8MP photographs at 30 frames per second one second before and one second after pressing the shutter button, giving you a total of 60 frames to select from when pushing the shutter button.
- 4K Burst (S/S): 4K Burst (S/S): Using this mode, you may watch your 4K video while pausing at a predetermined point. Then, using the shutter button, you can select a single frame from the movie and save it as a single 8MP frame. This mode is the most similar to the 4K video recording method.
The DMC-GH4 is equipped with a number of different connection terminals, including 1/8″ microphone and headphone jacks, among others.
A mini HDMI connector, an AV output, a flash sync terminal, and a 2.5mm remote controller jack are also included on the camera’s back panel.
SD Cards with UHS-I Class 3 performance is supported.
In addition to SDXC, SDHC, and SD Memory Cards, the DMC-GH4 makes use of a range of other high-performance recording media.
The UHS-I Class 3 (U3) card is the fastest of these cards and is suggested for utilizing high-bit rate video recording modes with bit rates greater than 100 Mbps.
Burst shooting at a high rate of speed
Using the mechanical shutter, the DMC-GH4 is capable of high-speed burst shooting at 12 frames per second in single autofocus mode for up to roughly 40 RAW or 100 JPEG shots, as well as 7.5 frames per second in continuous autofocus mode.
This allows you to record subjects that are moving quickly while maintaining sharp focus. When utilizing the electronic shutter, you may capture images in bursts of up to 40 frames per second.
Control of the highlights and shadows
By rotating the front or back dials, you may individually modify the highlights and shadows. In addition to the three pre-programmed patterns, three other patterns of settings can be created.
In order to provide intuitive control, the shutter button is positioned around the exposure compensation, ISO sensitivity, and white balance settings, which allows for quick and easy operation while looking through the viewfinder. Button Layout Additionally, a programmable function button is accessible.
- When using Post Focus settings, photographers can select the in-focus region of the image after the image has been captured.
- Time-lapse photography and stop motion animation captured in-camera
- The maximum shutter speed is 1/8000 second.
- Synchronization of the built-in and external flashes at 1/250 second shutter speed
- Face / Eye Detection Automatic Focus
- External Flash Burst facilitates the use of sequential flash bursts with on-camera equipment that are compatible.
- 1-Area focal point magnified by a factor of ten
- English and Spanish are the two languages that are supported.
