The set contains 3 clip-on lenses: fisheye, macro, and wide-angle. These lenses can be attached to the camera of a laptop, tablet, or mobile phone, compatible with most phones. Most mobile phones cannot focus at the close distance needed to photograph ants, but with this lens, you can take extremely close-up photos of them. Make sure to have proper lighting directed at the subject, and it’s best to remove any phone case so the lens fully covers the camera without casting a shadow around the edges of the photo.
