Electronic (OLED) Viewfinder on Canon EOS R100

Canon EOS R100 has a built-in 0.39" Electronic (OLED) viewfinder with 2,360k dot resolution. It has a 100% coverage and 0.95x (0.59x 35mm equivalent) magnification. There is no built-in or optional viewfinder available on Sony FX3.

Canon EOS R100 features a 24.1 megapixel APS-C CMOS sensor with dimensions of 22.3 x 14.9 mm and a total area of 332.3 mm². Its native ISO range is 100 - 12,800 and expands to 100 - 25,600 in boosted mode. Sony FX3 features a 10.2 megapixel Full Frame BSI-CMOS sensor with dimensions of 35.6 x 23.8 mm and a total area of 566.4 mm². Its native ISO range is 80 - 102,400 and expands to 50 - 409,600 in boosted mode.

Sony FX3 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 R100 is equipped with DIGIC 8 processor and can take pictures up to 6000 x 4000 resolution. Sony FX3 is equipped with BIONZ XR processor and can take pictures up to 4240 x 2832 resolution.

Lens Mount

Canon EOS R100 has Canon RF lens mount and Sony FX3 has Sony E lens mount. Due to APS-C sensor in Canon EOS R100 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 FX3 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.

No Low-Pass Filter on Canon EOS R100

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Canon EOS R100. 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 FX3

Sony FX3 has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS). 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 2.4 GHz on Canon EOS R100, Wi-Fi 5 802.11ac/b/g/n 2.4/5 GHz on Sony FX3) 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.
