The right lens
To maximise the background blur effect, it is best to use a fast lens, ideally with an aperture of f/2.8, f/2.0, f/1.4 or higher. Please note the following: The faster your lens, the shallower the depth of field of your camera's image, i.e. the area in the depth of field that is correctly focused. In other words, the smaller the aperture of your lens (i.e. the higher the f-number), the larger (deeper) the area of the image that is in focus. The distance between you and your camera and the focal length used also play an important role in depth of field. The shorter the distance, the shallower the depth of field; the same applies to the focal length.
If you are the only person in the room, the RF 35mm F1.8 IS STM Macro lens is a very good choice for a full-frame camera such as the EOS R6. On the EOS M50 Mark II with the smaller APS-C sensor, an EF-M lens with a focal length of 22mm shows the same image section as the 35mm lens on the full-frame sensor (crop factor 1.6).
The installation process
Installing the Webcam Utilities is a breeze: First download the software from Canon, then double-click to start the installation process - that's it! By the way: If you have installed the beta version of the Mac software, there is no need to uninstall it. The new version will completely overwrite the existing beta installation.
Camera settings
Switch your camera to video mode and select Full HD (FHD) with 25.00 or 50.00 fps as the video quality in your camera setup. The auto-power-off function should be turned off and the focus mode should be set to Movie Servo AF. For ISO settings, select automatic mode 'A'. This allows the camera to respond automatically to changing lighting conditions.
Connect your camera to your computer using a USB cable. In your video conferencing software (Zoom, Teams, Webex, etc.), select "Canon Webcam Utility" as the video source in the settings.
For longer web conferencing sessions, it is worth using a continuous power source rather than battery operation. Power adapters are available as Canon accessories for your camera.
Tip: Your video transmission will look more professional if you look into the camera while speaking or listening. Try to position the camera at eye level and close to your screen. Use a tripod if necessary. Ensure that the cables are routed properly to avoid any risk of falling.
Good lighting is also important. An LED video light from a specialised retailer, mounted at an angle of about 45 degrees to the side and slightly raised, is ideal. The same rules apply to lighting as for photography. A soft, directed light is ideal for a videoconference with people.
Finally, you can improve the quality of voice transmission by using an external microphone.
