www.orphancameras.com ZORKI-4K is a single-lens rangefinder camera intended for taking various amateur and professionalpictures on black-and-whitefilm. The camera is provided with a shutter setting lever and a self-timer 'rM, "X'rand is and synchronized. The viewfinder and the rangefinder of the camera have a common field of view and the camera eyepieceis provided with a device for adjusting it according to a particular eyesight. Such a design of the viewfinder ensures perfect focusi-ngat the moment of picture taking. The lens is focusedby turning its focusing ring. In so .doingthe range- finder operatesautomatically irrespectiveof the focal lenglh of an ln- terchangeablelens. The camera uses a new type of a take-up spool to simplify the camera 'loading. The carnera acceptsstandard cassetteswith invariable slit. The camera is delivered in two variants: with INDUSTAR-50 or JUPITER-B lens.View original page 3
