This is a set of four 58mm HAKUBA filters in a carrying case. These filters were used frequently, so they show considerable signs of wear. All four filters have minor dust-like smudges and linear wipe marks due to deterioration of the coating, but I don't believe they will significantly affect image quality. The set includes the following: 1. MC Lens Guard 2. MC Skylight 1B 3. MC UV 4. Circular Polarizer PL Sample test shots corresponding to the numbers above are included at the end of the product images for your reference.
