Sony a7R III Tested – Shooting a Mini Documentary

December 29th, 2017 Jump to Comment Section 34

Slowly but surly we are approaching the end of the year, and just before saying goodbye to 2017 I wanted to clear my desk and publish my impression and footage taken with the Sony a7R III.  The camera is currently shipping and during my last visit to Japan I had a chance to test it.

Unfortunately, the camera I was given by Sony was a local one – meaning, the menu structure was all in Japanese and there was no easy or fast way of changing it to English. So after receiving it I made sure that I’m adjusting some basic settings like resolution (4K UHD), picture profile (S-Log 2), frame rate, (24p) and such correctly. However, because of the limited understanding of the menu, I wouldn’t name my article a full review but rather ask our respected audience to look at my observations and footage as me just sharing some first impressions.

Alongside of having the Sony a7R III camera, I also asked for the new Sony 24-105mm f/4 lens as I wanted to see how well (or not) those are working together. I was pleasantly surprised to see that this combination is very easy to use and although it is an f/4 lens, together with a (very) lowlight sensitive a7R III, the results were impressive.

Overall camera improvements and impressions:

  • The new, larger a9-like camera body size is easier to handle and the inclusion of a new higher capacity battery is very welcome.
  • The second SD card slot is now active in video mode too and allows the recording of a backup simultaneously on card B while shooting on card A. That means that card A can be set to record 4K with proxies, and the same for card B at the same time. Also, it now has a relay feature for movie recording, meaning that the recording goes on to the other card, if one of the cards becomes full. However, this camera still has the typical 29:59 recording limit per clip.
  • The new camera now incorporates 2 USB input/outputs. One of them is for fast data transfer (USB 3.1) and the other can serve to charge/operate the camera from a computer or external battery pack
  • Both full frame and super-35 modes produces nice looking videos with the edge to the later. I like this combination and the ability to switch between both according to your shooting needs
  •  S-LOG3 is now supported but I wouldn’t recommend using this setting as this is an 8 bit camera
  • HLG (Hybrid Log Gamma) picture profile was added for producing instant “out of the box” HDR (High Dynamic Range) content
  •  The LCD is now a touch screen, allowing ‘tap to focus’ as well as the ability to drag your thumb across the panel while using the EVF to pinpoint specific locations for focus
  • Improved autofocus function. I can report from first hand that this is working very well in most cases

While having the camera for a relatively short time, it always felt as being a very responsive flexible working tool. No matter what I filmed with it and at what time of the day/night, the camera always produced nice looking video images.

What needs improvement:

What I would like to see being improved is the stabilisation system. Shooting handheld à la tripod mode pointing at a subject functioned well but when moving (walking) and following a subject, there is still some improvement to be made. It is also worth mentioning that’s like its predecessor, the Sony a7R III does not add any new frame rates so if you are in the market for a camera that can shoot in 4K and 50/60 frames per second, then this one is isn’t the one for you. Also, the rolling shutter doesn’t seem to be improved at all, unfortunately. I also noticed still some moiré on the full frame shooting mode which is the one I used.

Sony a7R III


Sony did quite a bit to improve the visual quality of their 4K video in the A7R III from its predecessor, and in my opinion it is now the best hybrid camera they ever produced. I’ve seen professional photographers showing some amazing photos that were captured with it and I can certainly report from first hand that the camera performs very well in different filming conditions. (And for those who are concerned about the overheating issue, well, it did not occur while I was shooting but this might be meaningless as we are all working in a different space and under different temperatures).

So, if this camera is so nice to work with, is there any obstacle in getting it? Well, the answer might be its’ biggest “enemy”,  Sony’s own non (yet) existing camera, namely, the a7S III. If I was currently in the market for a new Sony full frame mirrorless camera that can shoot video, I would certainly have in mind Sonys’ past tradition of labeling the a7S family of cameras as “video orientated” and “low light killer”, so while the a7R III is an excellent all around performer, Sony will have to offer something extra in order to capture the heart of filmmakers with the future a7S III. How valuable this extra feature is yet to be seen, but the knowledge that Sony is running 2 very similar yet different camera lines might be enough for many to delay their purchasing decision and wait for the next best thing from the same company.
