Sony A7S III – Everything is redesigned, but it’s still based on the idea of using a relatively low resolution 12.1 megapixel full-frame sensor to provide insane light sensitivity.

Sony A7S III Design

By: Sony

Now inside is a new exmor-r cmos sensor which uses a backside illuminated design. 

bringing twice the readout speed of a conventional sensor. everything on this camera is faster and cleaner due to the bionz x processor which is eight times faster than the bionz x. 

one huge benefit of this setup is that rolling shutter is effectively eliminated, which is a huge improvement over the a7s II. 

Sony A7S III is a relatively compact but impressive package. It features a body builder similar to the A7S II

For the beginner consideration

one of the dedicated buttons on top of the handle has been replaced with a large recording button,

which adjusts and renders the scene stable for this camera’s strong emphasis on video shooting.

There is a control wheel at the top of the handle, joined by an on and off switch, C2 button,

and dials for both mode and exposure and you can lock both whenever you want

Unfortunately, we did not get the confirmation of the work of the camera with rain,

but Sony assured us that it can handle the spray, and all the ports are under rubber covers to face the spray, and it is located on the left side of the camera when carried forward.

Screen

Sony A7S III Screen

The A7S III has a screen – it beautifully crosses, turns around and top like a dream.

With a precision of 1.44 million points, it is considered to be extremely sharp.

The A7S III also features an impressive touch user interface.

Thanks to the logical hierarchy of menus, it is easy to operate with a four-way finger or disk. It is really a very welcome inclusion.

But despite one thing we don’t understand is that the screen isn’t in a 16: 9 aspect ratio rendered that the A7S III is a video-focused camera.

image and Video

Sony A7S III Video Options

overall image quality on the A7S III is stunning, on the still side of things images are super clean and sharp. 

colours look vibrant but natural and you honestly don’t have to work hard to get a great image out of this camera

the sensor can reach deep into the dark capturing natural and ambient lighting that you simply can’t with other cameras. However it’s the supporting features such as fast autofocus that really make the A7S III effortless to use both in stills and in video.

As you can imagine there’s a lot to discuss with video. we’re still looking at a maximum 4k resolution with the camera which personally I think is still more than enough for nearly every shooter. 

all resolutions and frame rates can provide 19 bit 422 colour, compared to the previous model and its 8-bit recording 10-bit colour means smoother colour gradients, and allows you to push a colour grade much more.

Video options and Movie settings

Sony A7S III Performance, Movie Setting and Video Options

we have tons of video options on the camera, so first off is file format, we have all of the xavc formats. 

The new ones are the xavc s format which is an hevc codec. and that gives you a lower bitrate of the same quality.

so it helps you use smaller capacity cards, or if you even have slower cards this might actually be good for you. 

going down a little bit we have the standard xavc s 4k and HD flavors, these are the regular codecs that give you long off encoding. 

and then down below we have the intra frame versions, so these are very high 609 megabit recordings these require a v90 sdxc card or a cf express type a. 

we have the actual movie settings, there’s a frame rate selections and none of this is tired of your codec or your resolution. 

so this is all independent, i can go back to 24p for regular recording and down is your bit depth. you pretty much get the usual 42 to 10-bit for 208 bit and also a 60 megabit 4208 bit as well. 

Obviously for this we’re going to stick with 42-10 bit all the way. perfect for s-log recording, you no longer have to settle for 4208-bit.

Sony A7S III Performance

Sony A7S III features impressive performance in low-level lighting, the camera has the ability to handle stunningly high sensitivity well.

The low illumination capabilities of the A7S III make sense. Sony has created a new 12.1-megapixel sensor with huge pixels spread across a full-frame area of ​​35 mm. But these specifications are not new at all, but with the weak read speeds of the A7S II sensor, a backlit architecture capable of absorbing a lot of light, and a new Bionz X processor that powers things, the low-light boost is not surprising.

Sensor’s accuracy

it means that the A7S III cannot record 6K video, not to mention 8K, and instantly place it behind the Canon EOS R5 on that front. However, what he could do is record for a very long time.

Out of the 759 phase detection autofocus, this focus is far from advanced eye tracking, which is 30% faster than previous Sony cameras.

With Sony ZV-1, we haven’t had any issues registering for more than 30 minutes,

with the only limiting factors being card capacity, battery life and temperature,

and the good news is that we never had any warnings or hotter issues at all.
