The Black Eye G4 Travel Kit for smartphones consists of a set of 3 lenses: a portrait lens, wide-angle lens and macro lens. The clamp works like a clothespin and places you over the camera of your smartphone. For various camera effects, turn one of the supplied lenses on. The portrait lens zooms in to 2.5x so you can create lifelike portrait and street photos. With the wide-angle lens you capture vast landscapes thanks to the angle of view of 120 degrees. The macro lens with 20x magnification makes sharp pictures of the details of your subject. Thanks to the coating on the lenses you have no reflections on your images. The universal clamp works with smartphones, tablets, laptops and devices with dual lenses.
