This section shows those features and specifications which are the reason to choose Leica Q3 over Canon EOS R100.

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 R100 and Leica Q3 have 3.0" screens with 1,040k dot and 1,843k dot resolutions respectively. Canon EOS R100 has a Fixed screen Leica Q3 has a Tilting screen which makes it very useful for photography purposes but not so useful for video shooting. Leica Q3 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.

Viewfinder

Canon EOS R100 has a built-in 0.39" Electronic (OLED) viewfinder with 2,360k dot resolution and Leica Q3 has a built-in Electronic viewfinder with 5,760k dot resolution. They both have 100% coverage.

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. Leica Q3 features a 60.3 megapixel Full Frame BSI-CMOS sensor with dimensions of 36 x 24 mm and a total area of 576 mm². Its native ISO range is 50 - 100,000.

Leica Q3 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. Leica Q3 is equipped with Maestro IV processor and can take pictures up to 9520 x 6336 resolution. It can also take pictures with lower resolution like 36.5 MP: 7404 x 4928, 18.6 MP: 5288 x 3518 with 3:2 aspect ratios.

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.

Leica Q3 has an image stabilization.

Built-in Wi-Fi

Cameras have built-in Wi-Fi (802.11b/g 2.4 GHz on Canon EOS R100) 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

Canon EOS R100 and Leica Q3 have built-in Bluetooth 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.

NFC on Leica Q3

Leica Q3 has Near Field Communication (NFC) technology which simplifies the process of pairing it with other NFC-enabled devices like smartphones or tablets. It allows to quickly transfer photos and videos or remotely control the camera from compatible device. NFC can also be used for authentication and security purposes. It can verify your identity before accessing certain features or transferring sensitive data. It can be used with NFC-enabled accessories as well, such as lenses, flashes and GPS devices.
