Canon EOS R6 Vs Sony A7III

Full-frame cameras are dominating the professional and flagship models, but you can find many that are more pocket-friendly like Canon EOS R6 Vs Sony A7III. These cameras are good for hybrid photography, easy to use, produce excellent pictures, and overall perform well in almost any application. However, the price difference makes up some significant advantages and today we will see what they are and which camera you should get.

Full Frame Sensor

A full-frame camera refers to its sensor because it uses a 35mm sensor as opposed to smaller cropped sensors. Full-frame cameras have bigger and better pixels in general and larger pixels capture more color information as well as the incoming light for better efficiency. Full-frame cameras also give you higher depth-of-field control as it takes longer focal-length lenses to cover the format at any angle. Thus giving you the shallower DOP with the same lens and framing compared to cropped sensors. Additionally, the full-frame sensor gives you a wider angle to capture more of what’s in front of the lens.

About Canon EOS R6 and Sony A7III

Most camera manufacturers are focusing on their flagship models with a full-frame sensor, but both full-frame and cropped sensors have pros and cons, so neither is perfect, depending on the photographer’s preference and applications. Canon and Sony are two leading camera brands that continuously improve their systems. Canon EOS R6 and Sony A7III are some of the best full-frame cameras on the budget and mid-range section. These cameras have been around for a while, especially the A7III since it was launched in 2018.

Neither of these cameras is cheap and Canon EOS R6 is about $500 more expensive than A7III so you may wonder how this extra cost affects the camera. The R6 is arguably the best camera in its class because it gives a balanced combination of comfort, and excellent image quality, and is surprisingly pleasant for video recording. Does it make the A7III a bad camera? We don’t think so because even now, after 4 years of its release, the system is still solid despite being nowhere near the top performers.

The only reason that makes us want to recommend A7III is its price or if you are already in the system. Sony is well-known for its autofocus technology and while A7III is better than many other similar cameras in the price range, it is not yet beating R6 in ease of use. While EOS R6 is not the best camera for recording video, the A7III 4K 30fps and 8-bit internal recording are not as exciting as the R6’s 4K 60fps and 10-bit options.

Canon EOS R6 and Sony A7III Design

Not everyone considers the camera shape and handling when buying one, but it is crucial to adjust the comfort. The Canon EOS R6 and Sony A7III have a good grip and solid construction, but the tilting screen makes it fall shorter than R6. These cameras also have EVF which feels quite different. The A7III’s 2.3M dot EVF looks lackluster compared to R6’s 3.6M dot EVF. In addition, while either camera has a touch-screen, somehow Sony limits the use only to deciding the focus and not navigating the menu.

Canon EOS R6 and Sony A7III Camera Specs

Let’s see what the Canon EOS R6 and Sony A7III can offer starting from the camera specs. The R6 is a full-frame camera with 20MP resolution and a maximum resolution of 5472 x 3648. It records video at 4K 60fps and 1080p 120fps. Sony also shares the same sensor size, but it has a higher pixel count at 24MP and a maximum resolution of 6000 x 4000. This camera records 4K 30fps and 1080p 120fps. Additionally, either camera has in-body image stabilization for stills and videos.

Canon EOS R6 and Sony A7III Image Quality

The image quality from Canon EOS R6 and Sony A7III is fantastic and at a certain point probably more about personal preference on how you like the camera to process the image. At a glance there is no notable difference between the pictures from both cameras; details and colors are coming out well. Most people edit their images with computer software so you can do many things in post-processing. Full-frame cameras generally have good ISO performance and Canon seems improved a lot with R6, especially in mushy details.

Canon EOS R6 and Sony A7III Autofocus

For autofocus performance, you can’t go wrong with Canon EOS R6 and Sony A7III. Both cameras are impressive and few of the best in this price range even though Nikon also has very good autofocus in their recent cameras. The A7III’s continuous shooting produces a great hit rate of almost 100% and the eye-detect is still amazing. Overall, the real-time autofocus in A7III is very reliable. It might come out surprising but Canon’s autofocus system is just as good, if not slightly better in implementation than Sony’s.

The real time tracking is not as snappy as Sony’s, but the hit rate in continuous shooting is similarly fantastic. The factor that makes us prefer the R6 than A7III is the interface because Canon’s menu is easier to use and understand, so you can get around faster.

Canon EOS R6 and Sony A7III Video

Lastly, we want to peek into the video. Both cameras now offer 4K recording, but you can choose 4K 60fps on the R6. The A7III has an 8-bit internal recorder and the autofocus is reliable, so it is still useful for many applications. The R6 formerly had an overheating issue, but the firmware update already fixes this issue. The biggest deal with this camera is 60fps recording, internal 10-bit, and C-log for greater dynamic range. The autofocus works similarly impressively in video recording while the stabilization is also among the best.

Canon EOS R6 Vs Sony A7III

Full-frame cameras have pros and cons, but it is an excellent platform for photographers and hybrid users. The Canon EOS R6 and Sony A7III are impressive but different. We don’t have any issue with the image quality as they are equally fantastic. But, the R6 has few advantages over the A7III such as the overall user experience with EVF, screen, and menu. The R6 also shines brighter in video recording function with 4K 60fps, 10-bit internal recording, and C-log mode. The R6’s autofocus is also one of the best, and easier to use than Sony’s.
