The B+W 72mm Close-Up +5 (NL5) Filter serves for the seamless extension of the range provided by the NL 3 close-up lens on a 35mm main lens (up to Approx. 1:3.5). If you can tolerate a small gap after the NL 2 close-up lens on a 50mm main lens (approximately 1:4.4 to 1:4), then you enter a little further into the macro range with the NL 5 instead of the NL 4 (up to Approx. 1:2.6).
