This is a TTL automatic flash unit designed specifically for Nikon DSLRs, model number Viltrox JY-680N.
Its key highlight is its high cost-performance ratio: at an affordable price, you get a high guide number of GN50, support for Nikon i-TTL/Creative Lighting System (CLS), and off-camera flash functionality, making it ideal for users who don't want to spend a lot of money on a top-of-the-line Nikon flash unit from the start.
