This lens gives your OpenMV Cam the ability to see longer distances (e.g. zoom in). The standard lens that ships with your OpenMV Cam has a 115° field-of-view (FOV) which allows your OpenMV Cam to see more things, but, with less detail. This lens has a 25° FOV so it provides your OpenMV Cam with about a 4X zoom on any particular object.
The Telephoto Lens is great for any application where you need your OpenMV Cam to zoom in on some subject. For example, the telephoto lens makes it easy to do eye-tracking without IR light by zooming in on someone's eye making it easier to determine the direction their pupil is pointing.
