The Hoya Close-up Lens Filters allow the photographer to focus closer than what their lens typically allows. They function like a magnifying lens and are the simplest and most economical method for close-up shots.

• Available in various "strengths" (diopters).
• Can be used individually or in any combination to achieve extremely close focusing.
• The maximum magnification depends on the focal length of the lens as well as the close focusing capability of that particular lens.
• A +1 lens allows focusing closer than what your lens currently does.
• A +2 lens allows for closer focusing than the +1.
• A +4 lens allows for even closer focusing than the +2.
• The combination of a +1 and a +2 equals +3, while the combination of a +2 and a +4 equals +6, and so on.
