Features & Controls

Capturing the images for the GH4 is a 16.05-Megapixel Live MOS imaging sensor with a powerful image processor. This sensor allows the camera to capture incredibly high resolution images and 4K (4096x2160) video. The processor controls the camera's burst and creative shooting functions, increases image quality, and controls the camera's video capabilities. This includes allowing the capture of 8.8-Megapixel still images while recording 4K video.

Around the sensor is the Micro 4/3 mount system. This compact mount helps to keep the size of the camera very compact while still allowing you to attach all of Panasonic's Micro 4/3 lenses, as well as lenses from Olympus and others. The Micro 4/3 system is one of the only mirrorless mount systems that is shared by more than one camera company, greatly increasing what is available for it.

Panasonic has created a collection of 27 lenses and adapters for the Micro 4/3 mount system, giving you a vast variety of lens options for any situation. The adapters allow you to attach Lumix G and Olympus brand 4/3 lenses. This makes this camera a great addition to your bag or a great replacement to a larger dLSR. Panasonic's lenses feature their image stabilization system in the lens itself, not in the camera body. The focal distance of the camera depends on and changes with each lens you attach.

The GH4 features a small but fairly powerful pop-up lens unit. It boasts a guide number of 12 (ISO 100/m) and a sync capabilities of anything less than 1/250 of a second. There are several flash modes including auto Red-eye reduction and 2nd curtain. If the built-in flash is not enough for your needs, the camera does feature a hot shoe (shown further down this page).

Option #1 for composing and shooting with the GH4 is the OLED Live Viewfinder. With a full 100% field-of-view and incredibly high resolution, 2,359k dots, you will soon forget all about the optical viewfinder that you are used to. Inside the viewfinder you will see the exact same screen and information that is shown on the LCD screen (below). You get to see real time adjustments to your images as you change the camera settings, so you know exactly how they will affect your shot. At the bottom of the EVF is a sensor that knows when the camera is put up to your eye, so it can automatically turn itself on and off as you go to shoot.

Option #2 for composing and viewing your images is the free-angle, 3.0-inch OLED monitor. Sporting over 1,036k dots, this screen looks crystal clear and is very easy to see in all lighting conditions. It also makes it very easy to shoot video while on the move.

Controls on top: Starting at the left you have the locking mode dial with power switch. The button in the middle of the dial allows you to lock it into place so that it cannot be changed accidentally. On the right side you have the shutter release and command dial. The next row are the WB, ISO and exposure compensation buttons with the Fn1 button under them. All of the Fn buttons on the camera are programmable.

On the left side of the top you will find a dial that changes the drive mode of the camera (single, burst, bracketing, self-timer, etc.). On the right is the flash button, hot shoe and stereo microphone.

You will find plenty of controls on the back of the camera. Around the EVF you will find the playback button, Fn5 button (default EVF/LCD), AF/AE Lock coupled with the camera's focus modes and the dedicated video recording button. The GH4 does not have to be in a video shooting mode in order to capture video, it is always ready. For the most video control, you will want to use the manual video mode.


On the back right, you will find a second command dial, Fn2, Fn3, Fn4 and DISP buttons. The large 4-way controller is surrounded by another command ring that lets you search the camera menus with ease. Inside the 4-way controller is the Menu/Set button. This button takes you to the camera menu system and makes your selections once inside.


On the left side of the camera you will find the I/O ports. On top is a headphone jack, allowing you to hear the audio that the camera is picking up. This is very important if your sound quality is important. On the bottom are the high-speed USB and HDMI ports.


Just in front of the neck strap holder on the right side of the camera is the port for a remote shutter, allowing you to keep your hands off of the camera. Great for low-light and night shooting.


On top of the left side is a microphone input, allowing you add a wide variety of external microphones to the camera for better sound quality.


To store your images, the camera uses any SD/SDHC/SDXC type memory card. With the camera's incredible burst and video capabilities, you will want to use the biggest and fastest card you can get your hands on. We recommend at least a UHS-1 card. The camera is shown here with the Sony UHS-1, 32GB SDHC memory card that was used to test the camera.

Powering the GH4 is a 7.2V, 1860mAh rechargeable Li-ion powerhouse. In the GH4, this battery is capable of providing up to 530 images on a single charge. This is a fantastic battery life for an ILC, since they use electronic viewfinders instead of optical. Also included with the camera is the portable quick-charger, which allows you to keep more than one battery charged and ready to go with a little planning.

Another great accessory for the GH4 is the Lumix YAGH attachment. It mounts to the bottom of the camera and provides professional videographers with 2 XLR audio inputs and a 3G-SDI video output. This is a pricey accessory at $1,999.99, but can make all the difference in the right hands.
