The high quality optical magnifying lenses are diopters for close up photography, which shorten the close focusing distance of the lens. It allows the lens to go closer to the subject than before and to achieve a larger image scale. 
This macro filter set consists of four close-up filters allowing the photographer to achieve professional results at a low price.

All the four close-up filters are made of high quality optical magnifying glass cutting down the close-focusing distance of the lens.

The filters come in 4 different strengths: +1,+2, +4 +10.

Setting your camera to the smallest f-stop is recommended due to the narrow focusing range. This Kit also includes a high quality filter pouch with great protection for your filters.
