Kenko 37mm Close Up Filter Set +1, +2, +3 w/Case - Optical Glass - Made in Japan

With this close-up filter kit with filters in +1, +2, and +3 diopters you will be able to explore the macro photography world inexpensively utilizing your current non-macro lenses. Simply attach the filters to the front filter thread of your lens and it is transformed into a macro lens. They can also be stacked to further increase magnification* Hint: Depth-of-field is shallow so use as small an aperture as possible Effect: Regardless of the focal length of your camera lens if it's distance reading is set to infinity, focus is obtainable at a point equal to the distance from the tip of the camera's lens to the focal length of the Close-up attachment, but if the helical mount of the camera lens is worked focus will come a little closer.
