4K PHOTO Modes
Utilizing the G95's video recording capabilities, a trio of still shooting modes are available for recording continuous 8MP stills at a 30 fps shooting rate:
Post Focus and Focus Stacking
Another attribute of the 4K capabilities is a unique focusing method called Post Focus. Working in conjunction with the contrast-detection focusing system and the intelligent Depth from Defocus (DFD) technology, Post Focus records imagery as a 4K MP4 file at 30 fps and shifts the specific point of focus throughout the burst shooting in order to offer a range of distinct focusing ranges to choose from. During playback, via the camera's touchscreen, you can then tap the specific region of the image you wish to be in focus and an 8MP JPEG file will be created. Multiple individual files with different points of focus can be created from the original burst, and focusing assist functions can also be used to gain even more precise control over the specific in-focus region.
This technology also allows for producing focus stacked images in-camera to realize a greater depth of field, especially when photographing close-up subjects. In this mode, images are recorded and saved with varying points of focus and then blended together to gain an extended depth of field.
49-Area Depth-From-Defocus AF System
For accelerated autofocus performance, DFD (Depth-From-Defocus) technology is employed to quickly calculate the distance to subjects and adjust the focusing position, which enables continuous shooting up to 6 fps with continuous AF. This contrast-detection type focus method benefits both still and video recording modes, as well as subject tracking applications where subject color, size, and motion vectors are used to intelligently lock-onto the moving subjects and ensure precise focus. When working with portrait subjects, face/eye detection capabilities make it easier to photograph people and prioritize focusing as specifically as on a subject's pupil. The focusing sensitivity and speed can be adjusted to further improve performance with certain subjects. Additionally, AF sensitivity down to -4 EV supports working in low-light conditions
Benefitting manual focus operation, focus peaking is available that highlights bright edges of contrast with a colored outline for quickly recognizing your focus point, as well as Touch MF Assist for touch-to-focus operation. MF Assist can also be used to increase magnification by up to 20x for more critical focusing on specific subjects.

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.
Optimizing your recording for post-production color adjustment, the GH5S features a pair of gamma settings suited To capturing a wide dynamic range. V-Log L has been pre-installed on this camera and is used To capture a flat, neutral gamma curve well-suited for grading. Additionally, a High Dynamic Range mode, and Hybrid Log Gamma, can be used To record greater detail in both the shadow and highlight regions of a scene. Additional 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 Variable Frame Rate settings which provide speeds up To 2.5x slower in 4K (60 fps) and 7.5x slower in Full HD (240 fps). Also, a 4K Anamorphic mode is available, which will let you record in a proper 4:3 ratio for adjustment in post-production.
For greater recording versatility, the recording system frequency can be changed between 59.94 Hz (NTSC), 50.00 Hz (PAL), or 24.00 Hz (Cine) for worldwide use, and there is no recording duration limit for all settings. Three separate video control panels can also be usedshutter duration/ISO, shutter angle/ISO, or shutter duration/dBto match various worldwide production needs.
The GH5S is designed To be an expandable system, with multiple options available To help improve video recording capabilities. Examples of this are the included BNC conversion cable for syncing time code settings with an external device for multi-camera setups LINE input support via the 3.5mm mic input for using an external audio device and the optional 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.
