Panasonic GH5s vs Sony A7S II

Panasonic GH5s vs Sony A7S II

In the announcement, Panasonic claimed that this new Micro 4/3 camera is viable in lowlight and will excellently compete with the current lowlight king called Sony A7S II. However, there is huge difference in the sensitivity of these two cameras. One hand, Panasonic GH5s with 102400 and Sony A7S II has 409600, one big strength of A7S II, and the next is the competition of Full frame vs MFT. But GH5s comes with some advanced hardware that makes it promising camera in the lowlight areas. Last but not least, its unassailable Cinema 4K capability at 60 fps, making it the wonderful choice who want no compromise in the filed of videography.

Let’s dive deeper into the comparison of the two best lowlight cameras of the current time.

Panasonic GH5s vs Sony A7S II

Image quality 

 Whenever we want to get the highest possible image quality we love to go with Full-Frame sensor cameras with good lenses and we succeed to get the quality we mostly expect from the camera. Same here, Sony A7S II comes with 12 MP effective resolution which is backed up by Full-Frame sensor. On the other side, Panasonic GH5s has the similar 10.2 MP effective resolution but has High Sensitivity MOS sensor for enhanced image quality in low light, but still comparatively smaller than Full frame. Theory is, larger is sensor size clear sharper will be the images. So we do greatly expect the highest image quality by A7S II compared to Panasonic GH5s.

AF system

In AF terms, Panasonic GH5s would be the must loved camera since GH5 is working with contrast detect sensor only, which can give you instant focusing responses. Excitingly, Panasonic GH5 comes with a newly improved 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. GH5 is also based on same working principle since it uses a dedicated DFD hardware that work in synchronization with the contrast detect sensor featuring  distinctive 225 AF points, allowing the users to chose focus areas as per the specific composition required.

Sony A7S II, on the contrary, Sony A7S II is coupled with 169 AF points, which is consisted of 25 contrast-detection points and nine central AF points of the camera covers the entire screen, enhancing the users to focus lock on randomly moving subjects.

Rendering the same AF modes as of GH5. The GH5s also offers Post Focus function (If focus is not exactly as the user intended when the shutter is pressed) enables users to select the specific focus point even after shooting — effectively helps the users during macro shooting.

And other AF feature in GH5s is a 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.

ISO range

In the introduction, it was mentioned that Sony A7S II holds the ISO range of 409600. Well, it will really be excited to see if Sony A7S II with the highest ISO range can be outperformed by Panasonic GH5s because A7S II also has large sensor. By the way, it looks like A7S II is like a Rabbit with the Hat.

But, here is not the case that a camera with maximum ISO digit is winner! Panasonic GH5s announced atleast three years after A7S II and is specifically designed to compete with this Sony mirrorless camera. And you can see that Panasonic GH5s since a newly developed 10.2MP High Sensitivity MOS sensor for enhanced image quality in low light: Allowing up to 51,200 ISO recording without extended ISO (First in any camera).

The other feature in GH5s that makes the camera really stand out is Dual Native ISO, providing low range (400) and high range (2,500) ISO environments.

Shutter speed

One of the best advantages of faster shutter speed is it leads the photographers to take crisp and blur-free stills and videos with sharply focused subjects and defocused backgrounds. And you can see that Panasonic GH5s offers blazing fast 1/16000 seconds of shutter speed also ensuring that the users will not have to face the distortion issue in the images. But, A7S II avails the shutter speed of 1/16000 only.

Continuous shooting drive

The Panasonic GH5s offers higher frame rates of 12 fps, ensuring that camera can capture much more of the action each second, reducing the opportunity for action to blur. This results in producing sharper images in any kind of shooting (basically used in capturing the sports action of the intended players or subjects). Only 5fps of continuous frame rates A7S II offering us (very little for shooting faster actions of the target subjects).


Getting advanced than Panasonic GH5 and Panasonic G9, the Panasonic GH5s is essayed by fluent Cinema 4K (4096 x 2160p) @60fps, absolutely stunning! Panasonic GH5 is a must have camera for cinematographers since it features 3840 x 2160p @60fps with no time limit (not any other competitors in its range). It also gives you 4096 x 2160p @24fps. On the other side, Sony A7S II also record 4K but at 30 fps and offers very limited shooting time. So in this Field, Sony A7S II is lagging behind somewhere in the race.

Also, the GH5s currently the only camera that offers full HD @ 240 fps. Absolutely remarkable!

In one line, Panasonic GH5s is creatively one of the best cameras for the filmmakers and video enthusiasts.


Panasonic GH5s also allows you get 440 shots of different subjects at a time, whereas A7S II can get only 390 shots.


Photographers must spend bucks on Panasonic GH5s since the camera has everything to give you considerable sharp images and exceptional 4K video. Plus, it offers 12 FPS of burst rate for the action subjects. But A7s II gets attention for its notably large Full-Frame sensor. So based on our specification comparison we can only tell you Panasonic GH5s is the excellent camera for the video enthusiasts and the sports shooters.

Price difference is around $200 between these two cameras.
