FOREWORD-----------------

Featuring internal focusing (IF), the Medical-Nikkor 120mm f/4 IF is a close-up lens providing continuously variable reproduction ratios from 1/11 X down to 1X and, with the attachment of a single 2X close-up attach- ment lens, from O.8X to 2X. Because focusing is done internally, there is no extension in the lens barrel, making the lens extremely well-balanced and convenient to use. Exposure with the built-in ringlight is totally automatic. Once the ASA/ISO ring is set for the film speed in use, the flash output is automatically determined . Then, using a "guide number system," the diaphragm and focusing ring are coupled, so that the appropriate aperture for correct exposure is set as you focus. To let you know when the flash is recycled and ready to fire, an LED ready-light is built into the top of the lens barrel.

In addition, automatic imprinting of the reproduction ratio in use is possible via an ingenious system. Using a green LED and a miniature optical system inside the lens barrel, the ratio is projected through the lens and appears in the camera's viewfinder at the lower right-hand corner of the frame. Then, at the instant of exposure, the ratio is imprinted on the film.

Finally, this lens offers a choice of AC or DC power units for use indoors or out.

Although this complete close-up system is called a "Medical-Nikkor" lens, it has many other applications, including dental, scientific, industrial , and nature photography.
