Close-up Strength for NL +2
The +2 diopters of this close-up lens focus at a distance of 0.5m (1-5/8') with the lens focused at infinity. For the normal lens it is a stepless extension of its close-up range to approximately 1:4.5. On short to medium telephoto lenses it extends the NL1 close-up range seamlessly (with an 85mm lens to approx. 1:3.5 and with a 135mm lens to approx. 1:2.5).
Note! B&W close-up lenses are available in different "powers" (diopters)
