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 and Olympus Stylus XZ-2 iHS have 3.0" Tilting screens with 2,360k dot and 920k dot resolutions respectively. Tilting screen makes cameras very useful for photography purposes but not so 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 (available only on Sony Alpha 7R IIIA) 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. It has a 100% coverage and 0.78x magnification.Olympus Stylus XZ-2 iHS does not have a built-in viewfinder but an optional electronic viewfinder can be attached.

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. Olympus Stylus XZ-2 iHS features a 12 megapixel 1/1.7-inch CMOS sensor with dimensions of 7.44 x 5.58 mm and a total area of 31.1 mm². Its native ISO range is 100 - 12,800.

Sony Alpha 7R IIIA has 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. Olympus Stylus XZ-2 iHS can take pictures up to 3968 x 2976 resolution. It can also take pictures with lower resolution like 2560 x 1920, 1280 x 960 with 4:3 aspect ratios.

No Low-Pass Filter on Sony Alpha 7R IIIA

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Sony Alpha 7R IIIA. 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.

Image Stabilization

The cameras have a built-in image stabilization (5.5 stops of compensation in Sony Alpha 7R IIIA). On Sony Alpha 7R IIIA it means that you are still getting vibration reduction when it is 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 on Sony Alpha 7R IIIA

Sony Alpha 7R IIIA has a built-in Wi-Fi (802.11b/g/n, 2.4 GHz) 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.
