Panasonic GH5s vs Sony A7R III

Panasonic may begin a new series of camera but the A7 series from Sony keeps its legacy alive. Panasonic GH5s can be termed as one of the best video mirrorless cameras, but A7R III can sniff the victory first. At first its 42 MP high resolution with that full frame sensor and then again its excellent AF system, conquering the challenge in gentle way. GH5s is Panasonic’s Flagship camera that comes with some insane 4096 x 2160p @ 60fps really makes it stand alone camera and its new Dual native ISO feature makes it a promising lowlight device.

We are highly excited to see the close comparison of these two professional cameras in detail. Have a look!

Image quality

More effective resolution as well as Full Frame sensor, which we can say are the prime demands of the professional photographers. Here, in this comparison, A7R iii really rules that offers both the two things. And we can say that the still photographers can get images with maximum sharpness and clarity. Along with grabbing the rich detail images this Sony camera can also give the users the large print of the subjects. However, Panasonic GH5s is having low resolution so the still shooters who want no compromise in the image quality must go with A7R III. But since Panasonic GH5 is dedicated lowlight camera so it can come handy while shooting any event at night, means in lowlight.

AF system

Panasonic GH5s has dedicated AF hardware inside the core that is: DFD ( Depth from Defocus), but has contrast detect sensor only unlike the A7R III’s contrast  + Phase detect sensor. Well, the Depth from Defocus that works together with contrast AF technology that comprehensively calculates the distance of the subjects and analyze as per form, size and even motion of the subjects. The image sensor inside the core of GH5 features distinctive 225 AF points, allowing the users to choose focus areas as per the specific composition required and with the help of joystick located on the thumb position, they can control it easily.

Both are technically excellent! But Sony A7R III is peerless with its Fast Hybrid AF system (Contrast + Phase) that delivers far superior AF coverage, speed and tracking performance. Moreover, Moreover, A7R II offers comprehensive AF coverage that offers creative 399 focal-plane phase-detection AF points – that work together with 425 contrast AF points, allowing camera to achieve super fast focus response.

But if you go further, Panasonic GH5s same as of GH5 and G9 added Post Focus Function, which is highly beneficial for macro shooting. Next feature is Focus stacking Function enables users to take multiple images of the same frame with different focus points then you can combine them into one image with the defocus as you like.


Though GH5s has gritty 10.2 MP resolution, but it excellency in shooting at lowlight areas makes it something high class Mirrorless camera. Sony A7R III, on the contrary, can capture some beautiful and detail images in inadequate lighting condition all due to its large full frame sensor, but GH5s figures 204800 of ISO and the camera is also capable of dual ISO (400 & 2500). Means your lowlight photography will be greatly done.

Image stabilization

Panasonic might try to do something new and that is why it doesn’t incorporate the useful 5-axis image stabilization. And the camera also offers 4K video @ 60 fps means you have to find controlled environment when you shoot still and video with GH5s. Also, when a camera doesn’t incorporate the vibration reduction mechanism the owner needs to own some good lenses with OIS and also costly tripod so that he/she can get crispy and blur-free images.

Shutter speed

The big advantage of faster shutter speed is that it allows the users to shoot wide open at bright light. Moreover, the camera with faster shutter speed comfortably captures fast moving subjects. Here, in this comparison, you can see that GH5s avails faster shutter speed of 1/16000 sec, whereas the A7R III users have to rely on 1/8000 sec only.

Continuous drive

Sports photographers must be happy seeing GH5s burst speed that is 12fps. Yes! With the help of 12 fps, sports photographers can take advantage of every single frame to seize the subject and capture stunning sports photos. On the other side, A7R III offers 10fps only.


Panasonic GH5s starts a new era and is the first consumer level camera that offers 4096 x 2160p @ 60fps. Also, it can record 1080p @ 240fps. Best part is that there is no time limit in 4K recording. On the other hand, Sony A7R III lags behind in the race of videos. By the way, A7R III also offers 3480 x 2160p but at 30fps.


Panasonic GH5s lets you capture around 440 shots at a time, whereas A7R III allows you take almost 350 shots only in one time charge.


Panasonic GH5s has enhanced 4K capability and and has dedicated AF system that trades excellency in Price. On the other hand, Sony A7R III trades almost every particular section and is great camera for the still shooters. Passionate filmmakers and cinematographers must go with Panasonic GH5s.
