This excellent lens can be separated in two pieces (unscrewed): Macro part and wide angle part. So you can use it in both ways:
When it’s separated to 2 parts, the macro lens (without wide angle part) can be used for very detailed close up pictures.
When the two parts assembled as one, it becomes a professional wide angle lens, This 0.45x Wide Angle Lens with “MACRO” fits right over your camera existing lens system, allowing you to get more in the picture, include more of the landscape, more people in group picture, and interiors show more of the room.
