54° Lens for 580L HQ1 Cameras
This narrower focal view lens allows for a roll-cage mounted camera, situated further back in the car, to capture footage without creating a 'letterbox' view of the windscreen.
To install, remove lens cover and unscrew the old lens. Carefully screw the replacement lens into the camera body, using fine pointed tweezers or long-nosed pliers in the lens notches.
Once installed the lens will need to be focused: download a focus test card image (web search for "Focus Test Card" will bring plenty of results - download the highest resolution available) and print it out on good quality paper. The camera can then be correctly focused.
