To beexact, it can be mounted and trained onan object in thirty seconds, which is afeat impossible with the old-style appa-ratus. Furthermore, it can be rotatedeither in a horizontal ora vertical position, andit can take panoramicpictures at any rate ofspeed desired. These areonly two of many im-portant features whichshow the versatility ofthe machine. The ordinary motion-picture camera is limitedin operation to an angleof forty - five degreesabove or below the hori-zontal. It must be usedon a tripod, carefully lev-eled. In taking pano-.

Moreover, thepanoramic action is confined to rect-angular movements. Other restrictions arethe awkward lens ad-justments; the frictionof the film, which causesstatic electricity; exces-sive noise, making themachine impracticablefor nature and wild ani-mal photography; itsbulkiness and weight;the long time rec|uiredto assemble it and pre-pare it for operation; thelack of climate-resistingqualities; the numerousloose parts and acces- CURVEDARM UNIVERSAL JOINTsteel SUPPORTING RING PIECEVIEW FINDER DIAPHRAGMDIAL -FOCUSSINGDIAL FILMMETER
