Right: The close-up rangefinder fits into the accessory shoe of the camera and is used with a set of N supplementary
lenses (page 44).
Left: The table stand is a useful camera support for close-ups. The height of
the column is adjustable in the sleeve. A right-angle head can replace the
ball-and-socket head to direct the camera rigidly downwards for copying.
Right: The frame finder is useful for shots of moving subjects as it
permits observation of the subject in natural size. It fits into the
accessory shoe and can also be used with the supplementary N-lenses. It
incorporates parallax compensation.
Using the Close-up Rangefinder
1. Attach the close-up rangefinder to the camera.
2. Sight the subject.
3. Focus close-up rangefinder and attach supplementary lens.
4. Focus the camera lens.
5. Set stop and speed; check focus.
6. Release the shutter.
2. Approach the subject until the required subject area fills the blue-violet finder field. Hold the camera so that the
yellow field appears in the centre.
3. Turn the focusing wheel on top of the close-up rangefinder until the subject details in the yellow and blue fields
coincide. Note the position of the focusing wheel. There are three separate scales marked respectively with one, two,
or three lines for the NI, NII, or NI + NII lenses combined. Attach the corresponding supplementary lens or lenses to
the camera lens. When the scale with three lines for the NI + NII lenses is used, screw the NI and NII lenses on top
of each other over the camera lens. Filters, if used, should always be mounted in front of the supplementary lens.
4. Set the camera lens to the distance read off the focusing wheel. (This is not the subject distance.)
5. Look through the rangefinder to see if the yellow and blue images still coincide. If they do not, move the whole
camera forward or backward, but do not touch the focusing wheel again.
Other Close-up Lenses
As an alternative to the special N lenses, ordinary positive meniscus lenses can also be used. Any photographic
dealer or optician can supply a range of meniscus type lenses, to be put into a fitting filter mount. The lenses
suggested are +1 diopter, +2 diopters, +3 diopters.
