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

Canon EOS D30 has a 1.8" Fixed screen with 120k dot resolution and Sony Alpha 7CR has a 3.0" Fully Articulated screen with 1,037k dots resolution. Fully articulated screen makes Sony Alpha 7CR selfie and vlogger friendly and generally very useful for video shooting. Sony Alpha 7CR also features 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 7CR) 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

Canon EOS D30 has a built-in Optical (pentaprism) viewfinderSony Alpha 7CR has a built-in 0.39" Electronic (OLED) viewfinder with 2,359k dots resolution. Canon EOS D30 has 95% coverage with 0.88x (0.55x 35mm equivalent) magnification and Sony Alpha 7CR has 100% coverage with 0.7x magnification.

Canon EOS D30 features a 3 megapixel APS-C CMOS sensor with dimensions of 22.7 x 15.1 mm and a total area of 342.8 mm². Its native ISO range is 100 - 1,600. Sony Alpha 7CR features a 60.2 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.

Sony Alpha 7CR 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.

Canon EOS D30 can take pictures up to 2160 x 1440 resolution. It can also take pictures with lower resolution like 1440 x 960 with 3:2 aspect ratios. Sony Alpha 7CR is equipped with Bionz XR processor and can take pictures up to 9504 x 6336 resolution.

Lens Mount

Canon EOS D30 has Canon EF lens mount and Sony Alpha 7CR has Sony E lens mount. Due to APS-C sensor in Canon EOS D30 its crop factor is equal to 1.6x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.6. Due to Full Frame sensor in Sony Alpha 7CR 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.

In-Body Image Stabilization on Sony Alpha 7CR

Sony Alpha 7CR has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 7 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 on Sony Alpha 7CR

Sony Alpha 7CR has a built-in Wi-Fi (Wi-Fi 5, MIMO 2x2, 802.11ac/b/g/n, 2.4/5 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.
