We already listed pros and cons of each model. However, you may also find useful to look at their common strengths and weaknesses shown side-by-side.

Screen

Sony Alpha 7R IIIA has a 3.0" Tilting screen with 2,360k dot resolution and Sony Alpha 7R V has a 3.2" Fully Articulated screen with 2,360k dot resolution. Tilting screen makes Sony Alpha 7R IIIA very useful for photography purposes but not so useful for video shooting. Fully articulated screen makes Sony Alpha 7R V selfie and vlogger friendly and generally very useful for video shooting. Both models feature touchscreen which has advantages such as easy menu navigation, intuitive controls, quick setting adjustment and most importantly a Touch-to-Focus functionality allowing users to select a specific point on the screen where they want the camera to focus. This feature can be helpful for achieving precise focus in both photo and video recording.

Viewfinder

Sony Alpha 7R IIIA has a built-in 0.5" Electronic viewfinder with 3,686k dot resolution and Sony Alpha 7R V has a built-in 0.64" Electronic (OLED) viewfinder with 9,437k dot resolution. They both have 100% coverage.

BSI-CMOS Sensor

Sony Alpha 7R IIIA features a 42.4 megapixel Full Frame BSI-CMOS sensor with dimensions of 35.9 x 24 mm and a total area of 861.6 mm². Its native ISO range is 100 - 32,000 and expands to 50 - 102,400 in boosted mode. Sony Alpha 7R V features a 61.0 megapixel Full Frame BSI-CMOS sensor with dimensions of 35.7 x 23.8 mm and a total area of 566.4 mm². Its native ISO range is 100 - 32,000 and expands to 50 - 102,800 in boosted mode.

The cameras have BSI-CMOS sensor, short for Backside Illuminated Complementary Metal-Oxide-Semiconductor sensor. In traditional CMOS sensors, the wiring and circuitry are located on the front side of the sensor, which can block some of the incoming light. BSI technology flips this design by placing the photosensitive elements (pixels) on the backside of the sensor, allowing more light to reach the pixels. This significantly enhances light sensitivity and improves low-light performance. BSI-CMOS sensors are particularly effective in low-light conditions, as they can capture more light, resulting in brighter and less noisy images. This makes them well-suited for indoor and night photography. BSI-CMOS sensors deliver a higher SNR and reduced cross-talk.

Sony Alpha 7R IIIA is equipped with BIONZ X processor and can take pictures up to 7952 x 5304 resolution. Sony Alpha 7R V is equipped with BIONZ XR processor and can take pictures up to 9504 x 6336 resolution.

Lens Mount

Cameras have Sony E lens mount. Due to their Full Frame sensor their crop factor (also called lens multiplier) is equal to 1x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length.

No Low-Pass Filter

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on either of the cameras. This results in a slightly sharper image but may also introduce moiré patterns and aliasing artifacts when photographing subjects with fine, repetitive patterns or details.

In-Body Image Stabilization

The cameras have a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) (5.5 stops of compensation in Sony Alpha 7R IIIA and 8 stops of compensation in Sony Alpha 7R V). This means that you are still getting vibration reduction when cameras are paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.

Built-in Wi-Fi

Cameras have built-in Wi-Fi (802.11b/g/n 2.4 GHz on Sony Alpha 7R IIIA, Wi-Fi 5 MIMO 802.11ac/b/g/n 2.4/5 GHz on Sony Alpha 7R V) which allows to easily transfer photos and videos from the camera to other Wi-Fi-enabled devices, such as smartphones, tablets, printers, or computers. This eliminates the need for cables and allows for quick and convenient media sharing and social media integration. It gives you the ability to control your camera remotely using a smartphone or tablet. This is particularly useful for taking self-portraits, group shots, or capturing images in challenging conditions without having to touch the camera. Firmware updates can also be downloaded and installed wirelessly.

Bluetooth

Sony Alpha 7R IIIA and Sony Alpha 7R V have built-in Bluetooth (version 5 on Sony Alpha 7R V) which lets you to connect the camera to a smartphone or a dedicated remote control device. This allows you to remotely trigger the camera, adjust settings and controls remotely through a paired mobile app. While Wi-Fi is generally faster for transferring larger files, Bluetooth can be used for small, selective transfers, it can provide real-time information about your camera's battery status, memory card capacity, and other key settings directly on your paired smartphone or smartwatch.
