The Black Eye PRO Portrait Tele G4 is a portrait lens that's suitable for street photographers. You can attach the clamp to the camera of your mobile phone as if it were a clothes pin. Next, you can attach the portrait lens to this clamp. With this lens, you can easily create a depth-of-field effect in your photos: your subject will stand out from the background. You can get up to 2.5 times closer to your subject than with a regular smartphone camera. This way, you can take natural photos without any distortions. You can also prevent reflections with the coating on the lens. The universal clamp is compatible with smartphones, tablets, laptops, and devices with dual lenses.
