Let’s start this comparison article of the Sony a7r iii vs a7 iii with an in-depth overview of each of the two products and their major features. We will then move on to a deeper analysis of these features in a side-by-side format.
Sony A7R III Mirrorless Camera
The first thing that anyone would notice when shooting with the Sony a7R III is that it is capable of shooting in amazing details like never before. This is all thanks to the presence of a very precise and exact level of AF and AE tracking by the camera. Since it can shoot moving subjects at speeds of 10fps as well, this camera is excellent for stunning and clear videography.
Another feature that this product comes with is its Exmor R CMOS sensor that is back-illuminated. This ensures you get the optimal amount of light to enter the camera and this is made even more efficient thanks to the inclusion of a gapless chip lens. This allows more light to be brought in.
With this product, in terms of accessories, you will get a shoulder strap for better support and access, a power cord to easily charge your device, an eyepiece cup for protection, and a cable protector as well. This means you will end up saving quite a bit on extra attachments. This camera cannot exactly withstand really high or quite low temperatures but it works best in the 0 to 40-degree temperature range.
One more feature in this product that users will appreciate is the Bionz X processor. This ensures that you can get even quicker image processing and this means your processing speeds can be increased by 1.8 times. As we mentioned earlier, this product also is great for video as it can shoot and capture smooth and seamless 4K video with ease. This device can shoot and create image outputs in the following modes; JPEG, JPEG standard, JPEG Extra Fine, and RAW.
Sony A7 III Mirrorless Camera
We now move on to our next contender and this one is called the Sony a7 III. This camera has more advanced features especially when it comes to connectivity options. It can connect to your smartphone via Bluetooth technology. This includes compatibility with both android and iOS devices.
You will be pleased to know that this mirrorless camera is compatible with all Sone E mount lenses so you will not be limited in that regard. As we mentioned earlier, it can be connected to your wireless devices such as tablets laptops, and smartphones via Bluetooth technology.
The coolest thing here is that even though this camera works with speeds of up to 10fps, the process is super quiet as the shutter is nearly silent. The battery life for recording video continuously is around 200 minutes which is quite decent and you can get over 600 shots on a single charge.
It makes use of the Exmore R CMOS sensor so in many ways it is quite similar to its contender for today. This makes sure the noise is reduced in your images and quite a bit of clarity is restored. This device also offers 693 phase-detection and 425 contrast AF points.
In terms of the attachments and accessories that you can get with this device, there is an accessory shoe cap, a rechargeable battery, a shoulder strap for more support, an AC adapter, a body cap, a micro USB cable, and of course an Eyepiece cup as well. These are all wonderful added benefit that ensures you save up on your hard-earned money.
Now that we have a brief synopsis of each product’s features out of the way, let’s move on to the more in-depth comparison of the Sony A7R III vs A7 III.
Build, Construction and Size
The first category or aspect that we will be comparing these two Sony cameras in is their build, construction, and their size. We are starting with this because whenever you buy a camera, you will need to consider what activity you will be using it most for. If you are going to be traveling or moving around a lot then you don’t want a product that is too bulky. Size and weight are a big deciding factor when you are trying to find the ideal camera for your needs.
If we look at these 2 products side by side in this comparison article of the Sony a7r iii vs a7 iii, you will notice that they are certainly not that far off when it comes to weight! Sure their dimensions might be a little different however when it comes right down to weight, the Sony A7 III weighs around 650 g whereas the Sony A7R III weighs 657 g. And perhaps the best part is that these weights are inclusive of their respective batteries. So, if we had to compare the two based solely on weight, the difference is minimal.
If you want to get down to the nitty-gritty details, then surely the Sony A7 III is a little lighter than the Sony A7R III. However, as we discussed, this difference is not that big to cause a major difference between the two models. However, when it comes to buying a lightweight camera, you also have to consider how much weight a lens will add to the mix. Luckily for us, both of these models come with a lens that is of the same weight and since it is the E lens mount option, it won’t make a huge difference.
This is a very important factor for any camera because you want a device that offers maximum choices and options. The more connection options, the easier it will be to transfer, store, edit and share your images. This is why our readers will be pleased to know that both the A7 III and A7R III feature a USB-C port, make use of Wi-Fi and NFC technologies, and of course, also are compatible with Bluetooth. Other features that are pretty much the same, as can be made evident by our features overview is that both cameras make use of a maximum of 10fps with regards to their AF and AE tracking. When it comes to the main format of their buttons, everything is the same here too!
The one difference is that the A7R also has an extra button to lock the camera in shooting mode. This of course ensures that the user has more control over the device when capturing images and videos. Even when it comes to external connectivity, there is not much difference between the two cameras! With regards to this, the only difference is that the A7R III also adds in an additional flash port. The similarities include a USB Type C, a Micro HDMI Type D, a mic input, USB 2.0, and a headphone output.
Smart Sensor Features:
Next, let’s move onto the really exciting stuff; the smart features. Both of these devices are fitted with a backside-illuminated design and this ensures that even if you are in a dim setting, the sensor will be able to capture clearer images. The sensor will work just fine especially with the mirrorless design of these 2 cameras. There are some minute details between the 2 cameras though. With the A7 III, you will get to work with a 24.2-megapixel sensor whereas the A7R III comes in at 42.4 megapixels.
However, the reason why there isn’t a ton of difference between the performance of these models is due to both having full-frame sensors. This along with their impressive BSI chip technology ensures that they bring more light into the camera as compared to normal sensor technology. Not only is the processing speed faster in this case, but the images also are less noisy. So even with smart features, both the A7 III and the A7R III are not that different from each other!
To start with, we want to let the user know that while we have discussed a ton of similarities between these two cameras, the A7 disappoints in a very frustrating way. There is no electronic viewfinder on it as it is fitted with an OLED panel that is quite frankly quite outdated! The A7R on the other hand does have a viewfinder and this is the much faster option. In comparison, the OLED panel works at 60fps which is slower.
Now, moving to the similarities, both our options for today are equipped with 3-inch touchscreen displays that can tilt as well. However, the A7R III is the clear winner here as its display can manage a resolution of 1,440,000 dots whereas the A7 III grants around 921,600.
With this in mind, the difference still isn’t that big at the end of the day. Theoretically, the resolution on the A7R should be clearer and more vibrant. However, is that truly the case? In our experience, no because this isn’t a difference that the normal human eye can even register. So essentially this means that yet again, the A7R and the A7 appear to be evenly matched.
We discussed the shot ability of each camera in the features overview and when it comes to our opinion, the A7 III is slightly better than its contender for today. Again, the difference is not extreme because where the A7 can grant 710 shots via its LCD, the Sony A7R III can get you 650. The only reason why this might be a win over the other option is when you are in a high-stakes situation and getting the right shot is quite crucial.
Having that extra bit of battery life might come in handy! These cameras are fitted with an upgraded Sony FZ1000 battery and this has granted them an edge over previous models.
Image Stabilization Features:
To ensure that the image you get is high quality and does not blur in any way, it is necessary to invest in a device that offers adequate image stabilization. Sure, both options today might offer options for 4K performance but if you didn’t have features like the A7R’s five-axis stabilization system, the image would not be nearly as sharp as you would like. Luckily both devices offer a decent amount of image stabilization.
When it comes to shooting and making videos, both the A7 and A7R are excellent choices especially since they work very well on the move. You will get an excellent 1080p resolution if you stick to 120fps. You also have the option to get to brilliant 4K shooting if you shoot at 30 and 24 fps. While you cannot expect extremely high definition video quality from either of these cameras, they are still pretty good thanks to the addition of at least 24 fps especially when it comes to Sony’s mirrorless cameras.
When it comes down to it, there is no denying that the A7R is indeed more expensive when compared to its competitor. This might simply be due to it being a newer model. This is also the better option for some users since it is a great option for commercial photography. The results are high quality and the resolution is excellent as well.
One might even suggest that its winning amalgamation of high-speed performance, high resolution, and excellent results make the price worth it. It can certainly be used by professionals in the field as well and that can add a few price points into the mix.
On the other hand, the A7 is more affordable in comparison to the A7Rbut again the difference in the prices isn’t too much either. The price is just right when you realize that this camera offers amazing tools for photographers who work in low light conditions and who want to experiment during the nighttime. Similarly, also for sports-based activities or high-speed shooting, you would want to pick the Sony A7 III. When it comes down to price, we do not think that you will have to think too hard about this one but if you do have a tighter budget then the A7 III is your best bet.
