Feb., 1930] PROGRESS REPORT 247 available type of camera, projector, and accessory recommended for amateur use with 9.5 mm., 16 mm., and 35 mm. films.223 Amateur Cameras. — Interest in amateur movies continues to grow as improved equipment and film become available. The large list of finishing stations for regular and Kodacolor films recently published by the Kodak Company reads like the itinerary of a round-the-world tour.224 This Company has announced a 50 foot spring driven two speed camera which may be obtained with either an//3.5 or //1. 9 lens which are interchangeable with a long focus //4.5 lens. The //1. 9 outfit may be equipped for Kodacolor.225 A British made amateur cine camera is fitted with an //2.6 lens, a direct vision finder, and is designed to work at three speeds.226 An improved model of the Pathe "Baby-Cine" has been announced called the "Motocamera." The motor drive will run through an entire charge of film and the shutter and pull-down have been modified.227 Zeiss Ikon A.-G. has marketed a 16 mm. camera with an//2.7 lens. Film is supplied in magazines holding 33 feet.228 A combined amateur camera and projector has been announced.229 For projection the back of the camera is removed and the mechanism mounted on a stand with a motor, illuminating system, and shafts for 120 meter reels.

A few developments have been noted in the use of equipment for synchronizing sound with pictures for the amateur. McKay describes three ways of recording: (1) the use of wax disks with a portable phonograph, (2) the use of a microphone in conjunction with a loud speaker and a dictating machine, and (3) the second method with the addition of single switch control of the motors on the camera and dictating machine.235 Projectors. — The Victor 16 mm. projector claims as features a
