Panasonic Lumix GH5S Review

January 31, 2018 | Mark Goldstein |

Image Quality

All of the sample images in this review were taken using the 10M Fine JPEG image size option, which gives an average image size of around 5Mb.

The Panasonic Lumix GH5S produced images of outstanding quality during the review period. It offers noise-free images at ISO 80 to 6400, with limited noise starting to appear at ISO 12800, an excellent performance for a Micro Four Thirds camera. ISO 51200 and 102400 exhibit quite visible noise and loss of fine detail, while the fastest setting of 204800 looks much better on paper than in reality.

The various Photo Styles and Creative Controls allow you to quickly and easily customise the look of the camera's JPEG images before you take them, while the Intelligent D-range and HDR modes extract a little more detail out of the shadow and highlight areas. The night photograph was excellent, with the maximum shutter speed of 60 seconds and 30-minute Bulb mode allowing you to capture plenty of light.


There are 14 ISO settings available on the Panasonic Lumix GH5S which you can select at any time if the camera is in one of the creative shooting modes and the Extended ISO menu is set to On. Here are some 100% crops which show the noise levels for each ISO setting for both JPEG and Raw formats:

Aspect Ratios

Thanks to its multi-aspect ratio sensor, the Panasonic Lumix GH5s can shoot the same angle of view across four different aspect ratios, as shown below.










The Panasonic Lumix GH5S maximum shutter speed is 60 seconds and there's also a Bulb option for exposures up to 30 minutes long, which is excellent news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 30 seconds at ISO 160. The camera takes the same amount of time again to apply noise reduction, so for example at the 15 second setting the actual exposure takes 30 seconds.



Intelligent Resolution

The Panasonic Lumix GH5S's Intelligent Resolution feature identifies outlines, texture areas and soft gradation areas of the image and then automatically optimizes the edges and detailed texture areas while using noise reduction to make the soft gradation areas smoother. There are three available strengths - low, standard and high.

Off (100% Crop)

Low (100% Crop)

Standard (100% Crop)

High (100% Crop)

Intelligent Dynamic

The Panasonic Lumix GH5S's Intelligent Dynamic feature adjusts the exposure setting to record more detail in the highlights and shadows, with three strengths available - low, standard and high.
