With +4 diopters this close-up lens is
pretty powerful. With a focal length
of 0 mm it attains an image scale
of approx. 1:. With 100 mm focal
length this even advances to 1:1.,
i.e. into the true macro range. To
increase brilliance and sharpness,
stopping down by about two f-stops
is recommended. With the B+W
Close-Up Lens NL 4, calyxes ( ower
heads) already become too large for
the format.

With extremely high +10 diopter
power this close-up lens goes beyond
the normal scope. Its high refraction
is ideal for the short focal length of
digital photography. Even at a focal
length of just 0 mm you enter the
true macro range, with an image
scale of approx. 1:2. To increase
(depth of) focus, stopping down by
three f-stops is recommended. If
graduated sharpness is part of the
image concept, open apertures can
also be used.
