Product highlights:
B & W 48mm Close-Up 2 #NL 2 Close-Up Lenses. These lenses can be used individually or in any combination to achieve ultra-close focus. The maximum magnification achieved with these attachments will depend on the focal length of your lens as well as the actual close focusing capability of that particular lens. A +1 close-up lens will allow you to focus your lens somewhat closer than it already does; a +2 close-up lens will allow you to focus closer than the +1; a +4 lens will allow you to focus even closer than a +2. A +1 combined with a +2 will equal a +3, while a +2 combined with a +4 will equal a +6, and so on.
