First Impressions

This camera's High ISOs make shooting in the dark effortless. The low light performance on this camera is also quite spectacular. The pixels themselves can be quite large because there are only 12.1 megapixels, and they can gather in a ton of light. While personally using the camera with the 70-200mm G master lens, the images were very sharp and detailed. You can tell that sony has been doing much better in terms of their color science.



One new and surprising thing about the A7s III is that Sony has fitted a full-size HDMI port on the camera. This means no more days of carrying extra micro-HDMI cables that were prone to failing. There is also a dedicated microphone and headphone jack, a remote port, and the all-important USB-C Port.

For this camera, Sony decided to go with Dual CF Express Type A card slots (which can also be used as SD card slots). These new cards are fast, and not only will the camera benefit from the extra speed but when offloading the cards to your computer will also be beneficial.



The grip on the camera is a good standard fit for anyone. After personally taking this camera to the zoo, with the 70-200mm f2.8 G Master lens, I found the grip to be very comfortable for all-day carry and regular use.



When first glancing through the viewfinder, it is surprisingly large with a 9.4 million-dot EVF. The finder is considerably detailed and makes it easy to clearly confirm that the images were in focus. The back 3-inch screen has 1.4 million dots and an excellent articulating touchscreen LCD that flips out to the side.


While in use, the autofocus seemed quick and accurate. The autofocus does a great job of smoothly tracking and accurately switching subjects. The autofocus on this camera is one of its strong suits. Its ability to cinematically switch focus points is an essential plus. The new A7s III features a phase-detection autofocus system, where the previous generation, A7s II, did not.


The Menu System

Sony has created a major change with its menu system for the A7s III. It is easier to navigate the menus compared to previous Sony cameras especially while looking for specific settings to change. What is even better is that you can now use the touch screen to navigate the menu, and even scroll thru the settings.

Video Specs

The camera can shoot up to 4k 4:2:2 10-Bit up to 120p and can do 1080p up to 240p. The camera can shoot 16-bit raw if used with an Atomos Ninja 5. There are quite a few different log profiles for this camera, but using S-Log 3 is exceptional. The 4k 120 coming out of the camera is superb.

A nice new trick or feature for the camera is that you can have it automatically create a proxy file that’s fairly low res (in either 720p or 1080p). This will be a time-saver for most people since creating proxies or optimized media can take a long time, depending on your computer specs.
