It is a 4-piece close-up lens set that will allow me to get incredibly close to my subject. They are especially useful to capture the beautiful mini-majestic world I lost my heart to. I hope to use them to bring you more breathtaking images of the plants I study. I promise to take them with me as I travel the globe.
Other photographers wondering if they would prefer these above a regular macro-lens: the quality is not comparable, but if you are limited in packing weight (as I am when I am on a scientific mission) and still want to catch some of the macro-world, these lenses are an irresistible option. Major plus: they are not expensive at all.
