Cokin A72 Gray Diffuser Filter with Center Spot for Wide Angle Lenses A-Series.

Specifications:

The Cokin WA (wide angle) Grey Center Spot 1 filter has a clear center and diffused grey edges. These diffused edges will produce blur while leaving the center sharp. The filter effect is directly influenced by the f-stop and the focal length. A lens shot at f/1.4 will see a greater blurring effect than f/8.0 and an 85mm lens will see more blur than a 28mm. Additionally, a longer focal length lens will visually increase the size of the center spot area because it sees less of the filter area.
