Hoya Close Up Filters
Also known as close-up lenses, close-up filters prove to be convenient filters to have at hand. By installing these filters on whatever lens you are using at the moment, you can easily but effectively shoot macro. Or, by installing them on your macro lens, you can further shorten the working distance and get closer to your shooting object, thus making it look bigger on the final image. Close-up filters have different diopter values. The higher the diopter value, the more you can shorten the shortest focusing distance. You can also combine and use 2 or more close-up filters together.
