You have the standard A7 neck strap, you have the Z-type battery. This is the new Sony style battery that’s found in like the Sony A9 and Sony A7r III. Sony A7 III does not come with an external wall charger for the battery it only comes with plug-in type so you have to plug in the camera to charge it with the battery and the camera itself.

Image Sensor

So, under the hood of the Sony A7 III is a brand new 24-megapixel, backside illuminated Exmor R CMOS sensor, and that resolution is important; it represents the perfect balance for creating a detailed, high-resolution image, while also giving you plenty of opportunities to shoot at higher ISOs if you’re shooting in lower light or a mixed-light situation.

Now when there’s not enough light this camera is a beast. Because this camera is capable of shooting up to an ISO 204800 and it’s also expandable down to an ISO of 50 in the stills mode. If you’re going to be shooting video you have the capability of shooting up to about 50000 ISO expandable up to over a 100000 ISO.

The Sony A7 III features the all-new Bionz X image processor with a front-end LSI. This is going to give you much-improved color fidelity as well as high ISO performance and much faster autofocus.


So, one of my favorite things about the camera is the autofocus system. The Sony A7 III, it’s really like a baby Sony A9. It uses both contrast and phase-detection autofocus to give you accuracy and speed.

Sony A7 III features 693 phase detection points when you’re in the 35-millimeter full-frame format. As well in conjunction with 425 contrast-detection points. This is going to make sure that you have a reliable and quick AF, especially when tracking subject matter. Talking about tracking subject matter this camera takes a step up from the Sony A7R III and gives you even better-improved eye detection AF.

[2] Contrast-detection AF coverage (425 points)

With its ability for fast autofocus tracking the camera is also capable of shooting 10 frames continuously up to 177 frames. What I would recommend is utilizing the dual memory card slot especially the UHS-II card slot to make sure you’re able to keep up with your subject matter.

So, whether you’re using single-point autofocus for portraits or you’re using continuous autofocus for tracking moving subjects, the A7 III performs well above what any basic, entry-level camera should.

Video Features

There are so many filmmakers and creative moving-image artists that are using Sony products. The Sony A7 III doesn’t disappoint. In HD it can shoot up to 120fps for super cinematic slow motion. There’s even UHD 4K with HLG and S-Log Gamma.

For all video shooters, this is a full frame 4K capable camera. It uses the full width of the sensor you can get 4K to 30 frames per second. If you’re looking to slow down your subject matter you get 120 frames per second at Full HD.

So, if you’re the type of filmmaker that’s into slow motion cinematography, the in-camera image stabilization can also be very helpful for handheld sweeping movements.

Battery Life

Mirrorless cameras historically have not had the best battery life. Well the Sony A7 III borrows the same battery from the Sony A9, giving you longer shooting times in both photo and video.
