The Marumi Macro Achro 330 + 3 Filter DHG 72mm is a close-up lens made of tempered glass and features a multi-coating. This lens is moisture, scratch, and dirt resistant, making it ideal for close-ups and product photography. It shortens the focal length, allowing you to photograph objects closer. The lens offers increased sharpness and extra detail with difficult subjects such as glass and jewelry. It has a high ring that prevents unwanted light and reflections. With a diopter of +3, you can reduce the minimum focal length according to the formula: X : (D * X + 1), where X is the minimum focal length of your lens in meters and D is the diopter number on the close-up lens. For example: if your lens can focus from 55 centimeters and you use this close-up filter with a diopter of +3, then the minimum focal length is 0.21 meters, or 21 centimeters.
