Being the world’s first DSLM camera to record 4k videos, Panasonic Lumix DMC-GH4HEB-K truly meets the needs of professionals photographers. DMC-GH4’s new Live MOS Sensor and Venus Engine team up to reduce noise while raising resolution and improving color reproduction. Also, innovative DFD technology increases the speed of Contrast AF.
Panasonic Lumix DMC-GH4HEB-K photo quality
Due to the image processor Venus Engine, newly developed dramatically boosting its performance with new quad-core CPU that enables high speed signal processing required for rich video recording such as 4k.
Combination of new Digital Live MOS Sensor and the Venus Engine improves sensitivity at max. ISO25600, resolution and color reproduction, in order to achieve a higher picture quality.
The new 16.05 megapixel Digital Live MOS Sensor achieves high quality and sensitivity image recording with its quick response. Almost 50% higher speed signal readout suppresses rolling shutter effect when using electronic shutter or recording video. Taking full advantage of this system, gradation range is expanded by maximum 1/3 step at low ISO end. In addition, superior noise reduction allows max. 60 minutes long exposure.
Also, the DMC-GH4HEB-K burst shooting at 12 fps(AFS) with the maximum recordable images of up to 40 – including RAW, approximative 100 – excluding RAW and 7 fps (AFC) to capture fast moving subject just in-focus.
The Contrast AF system is advanced with the DFD (Depth From Defocus), technology which shortens the time to focus. It calculates the distance to the subject by evaluating 2 images with different sharpness level while consulting the data of optical characteristics of the current lens in a moment. As a result, ultra high speed AF of approximative 0,07 sec. is achieved. This improvement benefits more as focal length increases.
The DMC-GH4 also boasts newly developed high-precision, high-speed dual OLED (Organic Light Emitting Diode) displays for 2.359 K – dot LVF (Live View Finder) of approx. 1.34x / 0.67x and 3.0 – inch 1,040K -dot free-angle rear monitor. The OLED for the LVF boasts 10.000:1 high contrast for superior color reproduction.
Panasonic DMC-GH4HEB-K 4K video recording
One of the most important features of the new DMC-GH4 is the capacity of 4K video recording (Cinema 4K: 4096×2160 / 24 fps and QFHD 4K: 3840×2160 / up to 30 fps), video recording in MOV/MP4 or ultra high nitrate video recording at 200 mbps (ALL-intra) or 100 Mbps (IPB) without recording time limit, depending by the variety of practical functions required. For example, motion image can be recorded up to approx. 30 min depending on the recording format and the camera’s sales area.
Handling Panasonic DMC-GH4HEB-K camera
For quick control, 3 dials are equipped on the top of the camera and the main dial comes with lock structure. A dedicated button allows direct reach to exposure compensation, white balance adjustment for ISO setting. Also, 5 settings can be assigned to the Fn button.
The DMC-GH4 comes also with a variety of connection terminal, as the 3.5 mm microphone and 3.5 mm headphone jacks.
The Panasonic DMC-GH4 is capable of real-time image output on the external monitor via an optional HDMI micro cable simultaneously while recording video. In addition, Av outputs, flash sync terminal and 2.5 mm jack for remote controller are available. It complies with the SDXC / SDHC Memory Card UHS Speed Class 3 (U3).
It integrates Wi-Fi connectivity (IEEE 802.11 b/h/n) with NFC (Near Field Communication) technology. With the “Panasonic Image App”, remote shooting of photo / video is available with smartphone or tablet. It is also easy to embed geotag in the image after shooting. For the smartphone or tablet without NFC, the camera displays dedicated QR code on its monitor to complete pairing easily by reading the code.
The Interface Unit (DMW-YAGH0 is offered exclusively for professional or industrial workflow enabling more powerful video transmission. It complies with Full HD (4:2:2 / 10 bit) four parallel output or 4K (4:2:2 / 10 bit) output, both with time code. The 2ch XLR input terminals are also equipped for line or condenser microphone. Microphone volume can be controlled L / R separately.
Durability of DMC-GH4
The main structure of the DMC-GH4 is composed of magnesium alloy full die cast front / rear frame. It also features splash / dustproof construction thanks to the sealing on every joint, dial and button.
The shutter unit is also redesigned to be even more durable for approx. 200.000 release. It offers highest shutter speed at maximum 1/8000 not only to capture spur-of-the-moment for fast moving subject, but also to use high speed lens with open aperture even in outdoors to give impressive defocus. Both built-in / external flash can be synchronized with max. 1/2250 second shutter speed.

The most noticeable function of DMC-GH4 is the ability to use 1-area AF mode to focus on your main subject simply by touching it on the LCD. Another plus for DMC-GH4 is the Wi-Fi function. That lets you use your smartphone or tablet to change camera settings or even fire the shutter button remotely.
The circular control wheel on the rear is not particularly responsive, the Wi-Fi functionality is a little limited and the sheer number of options available can be initially confusing. Those are the few flaws of DMC-GH4 camera.
