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 III and Sony Alpha 5000 have 3.0" Tilting screens with 1,440k dot and 461k dot resolutions respectively. Tilting screen makes cameras very useful for photography purposes but not so useful for video shooting. Sony Alpha 7R III also features 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.

Electronic Viewfinder on Sony Alpha 7R III

Sony Alpha 7R III has a built-in 0.5" Electronic viewfinder with 3,686k dot resolution. It has a 100% coverage and 0.78x magnification. There is no built-in or optional viewfinder available on Sony Alpha 5000.

Sony Alpha 7R III 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 5000 features a 20.1 megapixel APS-C CMOS sensor with dimensions of 23.2 x 15.4 mm and a total area of 237.2 mm². Its native ISO range is 100 - 16,000.

Sony Alpha 7R III 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.

Cameras are equipped with BIONZ X processor.

Lens Mount

Cameras have Sony E lens mount. Due to Full Frame sensor in Sony Alpha 7R III its crop factor is equal to 1x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length. Due to APS-C sensor in Sony Alpha 5000 its crop factor is equal to 1.5x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.5.

No Low-Pass Filter on Sony Alpha 7R III

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

Sony Alpha 7R III has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 5.5 stops of compensation. This means that you are still getting vibration reduction when camera 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

Cameras have 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.
