When shooting macro in the range between 2.5x and 5x of the original, it is sometimes difficult to set the exact distance, especially when it is relatively dark. The LED ring light is simply attached to the front bayonet of the lens. This way you can see the subject much better and brighter and focus more accurately. As a power source, you can use any power bank (5,000 mAh lights for 6-7 hours) or a USB power adapter. The connection is made via included micro USB cable on the ring light.
