It’s compatible with zoom or prime lenses in the focal length range of 70-300mm (full-frame equivalent).  The close-up lens is the most effective way to achieve a closer minimal focal distance. The magnification achieved depends on the focal range of lenses, it will be higher with longer focal lengths. The magnification will be close to 1:1 when you focus at 200mm.\u003cbr\u003e\u003cbr\u003eTo use a close-up lens it is important to know the maximal and minimal distances at which you can focus because you will only be able to take a properly focused image within that range. The best working distance: 22-30cm.  We recommend using the close-up lens on telephoto lenses with an aperture of f\/8-f\/16 to achieve the sharped details.\u003cbr\u003e\u003cbr\u003eNiSi’s Close-up lens is made of double optical corrective glasses with apochromatic design and muti-nano coating to give advanced resolution and natural color with almost no purple\/green fringing both within focus and in bokeh.","brand":"NiSi","offers":[{"title":"Default Title","offer_id":46927113945263,"sku":"6972949370985","price":139.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6415\/2239\/files\/6972949370985_0.jpg?v=1779086598","url":"https:\/\/freshized.com\/products\/nisi-77mm-close-up-nc-lens-kit-ii-with-67-and-72mm-step-up-rings","provider":"Freshized","version":"1.0","type":"link"}
