One of the huge advantages of the GH5 is its expandability, including live monitoring and recording over HDMI while simultaneously recording internally to an SD card. It also comes with an HDMI Cable Lock Holder accessory. Shooters will have access to a 4K 4:3 anamorphic video mode at up to 60 fps, with firmware updates promised to upgrade this feature in the future. Other benefits include a dedicated GUI for videographers, which includes access to settings such as Gain and Shutter Angles, a waveform or vectorscope monitor display, and luminance level settings for 10-bit video. Finally, not to forget about audio, Panasonic has implemented a redesigned microphone with enhanced noise suppression and created a DMW-XLR1 XLR Microphone Adapter
that connects via the camera’s hot shoe and adds physical audio controls and two XLR inputs to the GH5.
These video capabilities are in addition to an extremely capable set of still-imaging features, including 4K PHOTO and 6K PHOTO modes with rolling shutter distortion correction for ensuring you don’t miss a shot. These record either 18MP stills at 30 fps using HEVC or 8MP stills at 60 fps using H.264 to provide a series of high-res stills for users to choose from. Also, it has a customizable 225-area Advanced Depth-From-Defocus AF system that is faster and more accurate, able to lock on in less than 0.05 second and, with the addition of a joystick to the camera, choosing an AF point is much faster and more intuitive. Speed is definitely a theme in the GH5, with 12 fps continuous shooting with AF-S and 9 fps with AF-C for up to 100 raw frames at full resolution.
A major change is the implementation of two SD card slots, both of which are UHS-II compatible, for auto switching, creating an automatic backup, or selecting which files are saved to which card for organization. Also, five-axis Dual I.S. 2.0 makes its appearance on the flagship GH series, here using a five-axis in-body stabilization system and a two-axis lens stabilizer. This system can provide about five stops of compensation for camera movement and shake, ensuring sharp, blur-free imagery.
In addition to this, the magnesium-alloy body has received numerous improvements, including the addition of freeze-proofing down to 14°F to the splash- and dustproofing. The rear 3.2" RGBW free-angle touchscreen LCD receives a resolution bump to 1.62m-dots while the OLED viewfinder is almost entirely revised, featuring much improved 3.68m-dot resolution, a large 0.76x equivalent magnification, and an eyepoint of 21mm. The physical controls have been optimized and now include a rear joystick and the placement of the video Record button on the top of the camera.
Additionally, the GH5 now offers a USB 3.1 port for fast image transfer and tethering. A new DMW-BGGH5 Battery Grip
is available for extending battery life and improving ergonomics during vertical shooting.
Those looking for wireless connectivity will be pleased with the introduction of 5GHz Wi-Fi and Bluetooth Low Energy that will make pairing with a smartphone much easier. The full-time Bluetooth connection can communicate with the phone to switch to Wi-Fi to transfer images to the smartphone—all automatically, as well as to auto geotag phones with the smartphone GPS, remotely wake up the camera, and copy and set settings from one camera to another.
