Strength of N1-CL1 Closeup Lens?
What is the strength of the N1-CL1 closeup lens?
The Nikon specs don't supply this information and I haven't been able to calculate consistent values from the information that Nikon does provide.
Would somebody please do the following measurement:
Hold the N1-CL1 near a wall to get an inverted image of something outside an opposite window and then measure the distance from the lens to the wall (in millimetres) to get the focal length.
(Diopter = 1000 / focal_length)
