Its waterproof, 0.9-inch diameter probe barrel with a built-in LED ring light and 2:1 magnification captures detailed close-ups in tight spaces that standard macro lenses cannot reach. The 18mm focal length provides a wide-angle perspective with a broad depth of field, rendering both subject and environment in focus for context-rich shots. This lens is best for product videographers and nature documentarians needing to film inside small cavities or capture immersive macro scenes.
