The Hoya Close-up Set 52mm includes +1, +2 and +4 (magnification) filters. Use individually or in any combination to +7 magnification.
Depth of field is shallow so use as small an aperture as possible.
We would always recommend cleaning a filter with a micro cloth to remove dust and general fingerprints.
Make sure the glass surface has to dust or grit on it.
Take a lens tussue, fold it one or twice (depending on size) and place a couple of drops of liquid lens cleaner on the tissue and wipe the tissue in a circular pattern starting from the center and moving out to the edge.
Immediately follow the first tissue with a new dry tissue using the same pattern.
Warning: We do not recommend using a micro cloth with any liguid cleaner because dust and grit an become trapped in the fibers and damage the lens or filter on subsequent uses.
