Where attendees or presenters may be far from the camera, will need a narrow angle HFOV. For instance a camera with a tele angle of 5 degrees will capture an image 26” wide at a distance of 25 feet from the camera (e.g. the head of a Boardroom table). This allows a good headshot with great focus on the speaker. A camera with a tele angle of 22.5 degrees will capture an image almost 10 feet wide at the same distance. This would not produce a headshot of any type and prevent focusing attention on an individual speaker. See the graphic below for examples:
