Panasonic Lumix GX800 Review - Performance

Panasonic Lumix GX800 Performance

The performance section is where we look at the image quality performance of the camera. Additional sample photos and product shots are available in the Equipment Database, where you can add your own review, photos and product ratings.

Speed - We took a number of shots to test the camera's responsiveness, from switch on to first photo, shot to shot, focusing speed etc. We take a number of shots and then use the average to ensure accurate and consistent tests, making it easy to compare with other cameras.

Shutter Response <0.05secs
Wide - Focus / Shutter Response 0.2secs
Full zoom - Focus / Shutter Response  0.2secs
Switch on Time to Taking a Photo 1.6secs
Shot to Shot without Flash 0.45secs
Shot to Shot with Flash 0.7secs
Continuous Shooting - JPEG
(shots before slow down)
5.8fps (47 shots)
Continuous Shooting - Flash N/A
Continuous Shooting - RAW 5fps (20 shots)

Shutter response is fast, as is focus. Continuous shooting is good at 5.8fps using the mechanical shutter, or 10fps when using an electronic shutter, and you can take a good number of shots before the camera stops shooting. 

Panasonic Lumix GX800 Sample Photos

Sample Photos - The GX800 has reliable exposure, and to extend dynamic range you can use the iDynamic or HDR options. There is a good level of detail in photos, and when using flash for portrait shots, there are minimal signs of red-eye. The selfie features are good, with the blurred background feature being particularly good, creating a blurred effect around the subjects face. Buddy mode automatically takes a photo when two faces are detected next to each other. 


Panasonic Lumix GX800 Lens test images

Lens Performance - The compact 12-32mm f/3.5-5.6 lens performs well and is capable of recording high levels of detail, even into the corners of the image when shooting wide-angle or with zoom, and you can read our full review of the lens here. There is a slight hint of vignetting in the corners, which can be corrected in camera by switching on shading compensation. Purple fringing and chromatic aberrations are very low with the camera automatically correcting for these problems. 

Macro performance of the kit lens is a weakness, with the closest focusing distance 20cm from the lens, and for more serious macro photography a different lens is recommended. When shooting with the sun in the frame it is possible to see some lens flare, however this wasn't a huge issue the majority of the time.


Panasonic Lumix GX800 ISO test images

ISO Noise Performance - For the lowest noise and best detail possible we would recommend using ISO100 to ISO800, as images have low levels of noise and good levels of detail. For lower light situations ISO1600 to ISO3200 still provides good results, although noise increases and detail is reduced. At ISO6400 noise levels become strong and we would recommend avoiding this setting if possible, although results may still be useful if resized and used on the web. ISO12800 and above is best avoided as noise is extremely high, and detail is low. 


Panasonic Lumix GX800 White-balance test images

White Balance Performance - Auto White Balance (AWB) performs fairly well under tungsten lighting with a warm result. Unfortunately the tungsten preset also gives a warm result, and it would be good if there was stronger colour correction here. AWB performs well under fluorescent lights, and there is no fluorescent preset available.

Panorama mode - The camera features an automatic panoramic mode, where you simply press the shutter release button and pan the camera from one side to the other. Results are quite good, although any movement in the frame will be shown in the picture. The resolution is reasonably good, and stitching is good. There are numerous effects available, and you can edit raw files in playback mode.


Video - You can record 4K UHD video at a resolution of 3840x2160, at 30, 25, and 24fps, with stereo sound, and video is recorded at 100Mbps as MP4 files. The camera doesn't feature in-camera image stabilisation, so if you want your videos to be steady, then you will need to use a lens with optical image stabilisation or a tripod. You can switch on Zebra pattern display, and monochrome live view. Video quality is very good, and there are a good range of options available. Additional videos can be found on the ePHOTOzine YouTube Channel.

In the lens, not in the body. A lot of M43 lenses do not have IOS as standard, especially non-Panasonic lenses, although there are some Panasonic lenses which are also missing this. It wouldn't be fair to list it as having Image Stabilisation on the spec page as it's not part of the actual camera spec.
