Nikon Z6 vs Sony a7 III Overview

Today’s comparison is the Nikon Z6 vs Sony a7 III. On specs alone, this is an extremely close match! They’re two mid-range mirrorless cameras. They were both released in 2018. And they remain popular cameras with photographers and video makers to this day.

At the time of writing, both camera models are also extremely close in price. For many, the choice may come down to which brand you are most comfortable with. However, new photographers and those looking for a change might also have to weigh up the pros and cons!

We recently named the Sony a7 III as our top camera for artists. Due to its high-performing processor and large sensor, it’s great for picking up details in the artwork. This applies to other photography niches which require detailed images.

A landmark mirrorless camera with a powerful sensor and fantastic features
from $1,998.00

The Nikon Z6 was the flagship camera in the Nikon Z series until the Nikon Z6 II was released two years later. It’s still a great model to consider.

Body and Handling

Starting with body and handling, both cameras are very close. The Z6 is slightly bigger in size measuring 134 x 101 x 68mm in comparison to the a7 III at 127 x 96 x 74mm. The Nikon model is also heavier by about 25g. These differences exist, but they are so minute that it’s unlikely to sway most people hunting for the best camera choice.

Nikon Z6 vs Sony a7 III Optics

There’s very little to separate the Nikon Z6 and Sony a7 III when it comes to optics specs. They both perform very well. They both have a Full Frame sensor. The sensor size is almost identical, but the Z6 has a couple of millimetres on the a7 III.

The Nikon Z6 is a bit ahead on points due to the very slight increase in resolution. It also can shoot 12 fps in burst mode compared to the Sony at 10 fps. Both cameras have a similar and highly adequate ISO and shutter speed range. Both have a minimum ISO setting of 50, which gives you wonderful detail and quality.  If you often shoot in low light, you won’t be disappointed.

Both models have a built-in image stabilization system which is highly desirable for many types of photography.

The Sony model offers more autofocus points. This can be desirable for those who shoot action photos as it can help you keep focus.

The higher the number of megapixels, the more detail the cameras sensor can capture.

Features and Benefits

Again it’s a very close call between the Nikon Z6 and the Sony a7 III. The Z6 comes out on top when we look at the features and specs in the table below.

Although both cameras have great features, the Nikon has a bigger screen size at 3.2″ compared to the Sony 3″ screen. Not only is it larger in diameter, but it also has a significantly higher resolution at 2,100,000 dots. This may not be a  deciding factor for many photographers, but that extra detail on the screen is definitely a nice touch!

Both cameras are weather sealed which means extra protection for those who like to shoot in less than favourable conditions.

Both cameras have Wi-Fi and Bluetooth connectivity, which is great for transferring images and sharing online.

Both the Nikon Z6 and Sony a7 III have adequate storage and battery features for most kinds of photographers. However, the Sony model comes out on top here. It’s dual memory card slots are a big plus. It also has over half the battery life of the Nikon model according to the official CIPA ratings.
