The Kalart Focuspot is an extension of the Kalart Rangefinder to focus in total darkness or under adverse light conditions.
When the Focuspot is switched on, a beam of light is projected through the Range Finder. This beam projects its filement of the bulb on the subject. This light is split in two by the Range Finder and the two pairs of filement are projected on the subject to be photographed. The beam act as a guide in locating and centering the image on the ground glass. The focusing knob of the camera is turned in the usual way. When the two light beams are superimposed on the subject your picture is in sharp focus. The camera may be held at any level.
To install the Focuspot, remove the cover on top of the Kalart Range Finder. Place the Kalart Focuspot as shown in the picture on the left and turn it into it's position. It might be necessary to remove the Tubular Finder or in some cases the mounting plate from the Graflite or Heiland Flash Holder. To connect the Focuspot to the battery case you'll need a
Graflex Double Post - Household Flash Sync Cord.
Replacing the little bulb in the Focuspot should not be a problem. Only one screw holds the two pieces together. To switch the Focuspot on, just turn the milled screw to the right. Make sure the battery case is connected on the right way to the focuspot.
