Sony FX3 FF Cinema Camera

So, in this review, I will explain how Sony FX3 can change your workflow and become your primary camera.

I will explain the camera’s pros and cons and some of the things that I’ve noticed about it that may or may not make a difference for you if you decide to buy it.

When I talk about cameras I really like to talk about the good, I never want to share the bad but first is the build quality.

It’s made out of high-end materials, the build quality is tied really close to the physical design. So if you are wondering Sony A7S III and the FX3 are the exact same camera on the inside, the internals on the FX3 is exactly the same as the A7S III, but they’re different on the outside.

there is a fan built-in on the FX3 with three different modes, there’s auto so when it needs to blow it will suck the air in and blow it out it sucks it in from the bottom and blows it out the side there’s off mode in case you don’t want it at all and then there is a minimum mode.

If you’re moving from photo to video there’s a switch and it takes about 8 to 10 seconds for it to move from photo to video or from video to photo.

So the buttons on FX3 are very easy to access basically every button is super customizable. And all the buttons and dials just feel really nice for me.

You can find a record button on the front, there are 1/4 20 mounts all over this camera, separate little doors for the full size HDMI port, and two full size XLR ports.

There is a door for the 3.5 millimeter microphone input, and the headphone output, a door for the USBC, and the multifunction USB port, and on the other side there are two SD card slots and both of these are combo ports, just like on the A7S III.

FX3 has a new layout for the main menu which gives faster access to key video menu items stand by movie screen puts all settings round your image similar to the Sony Venice EVF layout.


The FX3 has tally lights located in four different places there’s one on the front and in case you’re recording someone they can see that you’re recording them. there’s one on the back at the top you can set it up so that the LCD screen will show you the readout line when you’re recording.

there’s also a light up top by the new record button also on top they move the joystick it’s no longer on the back it is up top if you want to control stuff from there.

FX3 Image Quality

Let’s talk about the image quality that’s probably the most important thing about any camera. So, in my experience, the image quality from the FX3 and the A7S III is absolutely amazing. The image you get out of the Sony is really incredible it matches up pretty well with their cinema lineup.

The footage that’s coming out of the Sony FX3 is just so incredible this is a hybrid camera that is incredibly good at both photo and video.

Both cameras have incredible low-light performance, and full-frame sensors but FX3 takes still photos the same way that the A7S III does.

FX3 Autofocus

The autofocus is really what initially work on the Sony system it works great the image quality is amazing you can easily adjust the sensitivity you can make it really quick and sharp.

FX3 Sensor

FX3 features 4k up to 120 fps with a slight 10 crop, you can do 1080 up to 240 fps, there’s 16-bit DCI raw 4k up to 60p with a clean out and there is a dedicated cooling fan inside the camera, so, when you recording in 4k hq mode there is no issue you can not run into overheating with this camera.

The sensor on FX3 boasts 12 megapixels and the sensor with those megapixels is a little bit wanting in terms of still photo capabilities. And that 12 megapixel sensor is really what makes these such powerful video cameras.

So what I want to tell you here a sensor with fewer larger pixels equal better image quality, better low light performance, and less heat production. So that’s why cameras with these megapixels don’t really overheat.

In most cases, they work so well in low-light but cameras like the Sony A7 IV with a 33 megapixel sensor are way better for still photos, they can be prone to overheating in some situations. So the 12 megapixel sensor in terms of video is really one of the secret weapons of these cameras.
