Along with all these internal improvements, the body received some significant upgrades as well. For viewing and composing images both the 0.76x OLED viewfinder and 3.2" free-angle touchscreen received resolution bumps to 3.68m dots and 1.62 m dots, respectively. This will make shooting more comfortable and more accurate. The magnesium alloy body is now freezeproof to 14°F in addition to splash and dustproof. For fast image transfer and saving, there are now two UHS-II SD card slots. Additionally, for a completely wireless setup it offers both Wi-Fi and Bluetooth for advanced functionality when paired with a mobile app.
20.3MP Digital Live MOS Sensor and Venus EnginePacking in a newly developed 20.3MP Digital Live MOS sensor without an optical low-pass filter and a new Venus Engine processor, the GH5 claims to produce the best image quality to date from a Lumix camera. Using Multipixel Luminance Generation and Intelligent Detail Processing, it will maximize sharpness and details as well as accuracy in a variety of lighting conditions. It offers excellent three-dimension color control and precise noise reduction techniques to help with shooting at sensitivities up to ISO 25600. It also enables shooting speeds of up to 12 fps with AF-S or manual focus modes.4K Video RecordingThe GH5 is an exceptionally capable video camera in addition to its outstanding stills capabilities. The flagship feature is UHD 4K video at up to 60 fps, though another excellent spec is the ability to record 4:2:2 10-bit files at resolutions up to DCI and UHD 4K at 24/30 fps. A full-size HDMI port is present on the camera for high-quality output at 4:2:2 10-bit in all settings for use with external monitors and recorders. The camera also offers high bit-rate recording for highly detailed images free of compression artifacts.
For more advanced users, multiple picture styles are available to provide a more gradable image, such as CINELIKE V and CINELIKE D, as well as an in-camera LUT to make monitoring easier. Also, users will have access to overcranking and undercranking settings which provide speeds up to 2.5x slower in 4K (60 fps) and 7.5x slower in Full HD (180 fps). Also, a 4K Anamorphic mode is available, which will let you record in a proper 4:3 ratio for adjustment in post-production.
The GH5 is designed to be an expandable system, with multiple options available to help improve video recording capabilities. Examples of this are an optional V-Log L upgrade and separately available accessories such as the XLR Microphone Adapter that provides XLR inputs and physical controls through a hot shoe connection. Users can also use standard microphones and headphones via the 3.5mm input and output jacks.
