Now that we’ve taken a look at what Fuji X-T3 and Sony A7III have in common, let’s discuss some of the main differences:


As you probably know, Fuji X series of cameras have APS-C sensors, while the A7 line sports a full-frame sensor. With that said, Fuji X-T3 sensor has a bit more resolution (26MP) compared to 24MP on the A7III. Like we already mentioned both sensors have backside illumination, which means you’ll get better low light shots and dynamic range.

The great thing about Fuji X-T3 and Sony A7III compared to newly released mirrorless cameras from Nikon and Canon is the selection of lenses. Both camera systems have more than 20 native lenses made by Fuji and Sony for their respective systems, and there are many more lenses from other manufacturers such as Rokinon (Samyang), Zeiss and others.

Autofocus Points

Fuji X-T3 has 425 phase detection points that cover the entire sensor (100% coverage), while the A7III has 693 phase detection points with 93 percent coverage of the sensor and 425 contrast detection points. Sony used to have a big lead over Fuji when it comes to autofocus, but this doesn’t seem to be the case anymore, although Sony’s AF system is still considered the best in the world of mirrorless cameras.

Body Size and Weight

When it comes to body size, Fuji X-T3 is somewhat smaller, but the difference isn’t huge. Weight-wise, there’s a bit more of a difference – Fuji weighs 1.19 lb (539 grams), while the Sony A7III comes in at 1.43 lb (650 grams), and that’s with battery and SD card inside the bodies.

Burst Shooting

Fuji X-T3 has a slight edge in this department with 11fps compared to 10 fps on the A7III, when using the mechanical shutter. However, using the electronic shutter, the X-T3 can shoot up to 20fps and even 30fps with a 1.25X crop. Pretty impressive!

Video Recording

Besides being able to take amazing photos, both cameras have some great features for video shooters. Sony has in-body image stabilization, which helps a lot when you’re shooting handheld video. Unfortunately, Fuji lacks this feature.

With that said, Fuji X-T3 can record 4K at up to 60fps in 10 bit, while the A7III is limited at 30fps and 8 bit recording. The X-T3 definitely wins out in this department. Like we previously mentioned, both cameras can record in 1080p at up to 120fps.

Memory Cards

Electronic Viewfinder and Display

When it comes to the EVF, the X-T3 takes the win thanks to its 3.69 million dot viewfinder with a magnification of 0.75x. Although Sony A7III has slightly better magnification (0.78x) the panel has only 2.36 million dots. Refresh rate on the Fuji is also better.

The difference is minimal when it comes to the touchscreen display on the back. Fuji has a 1.04 million dot screen, while the A7III features a 0.92 million dot display.

Battery Life

As far as battery life goes, the difference is pretty big in Sony’s favor. Fuji is rated at about 390 shots per charge, and the Sony A7III can do 710 shots on a single charge, but most people claim they get even more shots on the Sony.


Retail price for the Fuji X-T3 is $1,499, which is great for the amount of features that you get with this camera. With that said, the A7III retails for $1,999 and that is an amazing price considering it has a full frame sensor. Both cameras will probably be selling well for quite a while, so we don’t expect any price drops anytime soon.

We hope this article helped you understand some of the main differences between the Fuji X-T3 and Sony A7III.
