Manufacturer description #1
The PRAKTICA LB is a miniature single-lens reflex camera for the 24 x 36 mm picture format. Its novel type of steel-bladed focal-plane shutter, which travels across the shorter side of the frame, has a range of speeds from 1 sec. to 1/1000 sec. and B. It is synchronized for the use of bulbs and electronic flash units. Owing to the extremely rapid movement of the steel curtains, the electronic flash can be synchronized at about 1/125 sec. setting to symbol ↯. The centre contact in the accessory shoe makes it possible to connect camera and flash unit without using a cable.
The pentaprism is firmly built in, and the focusing system with its Fresnel lens reveals a finder image of maximum corner-to-corner brightness. The microprism screen and a ground-glass area assure quick and perfect sharp focusing.
Additionally, the PENTACON PRAKTICA LB has a photoelectric exposure meter built in which is to be operated manually.
For use as interchangeable lens systems, the well-known PRAKTICA lenses are available. Up to a focal length of 180 mm they have automatic diaphragm control. In connection with the automatic mechanism in the camera they function as spring-diaphragm lenses which means that the diaphragm closes within the shortest time and opens again immediately after the shutter has run down. Through the instant return mirror the image is visible practically all the time, except for the short moment of the exposure.
Manufacturer description #2
This model corresponds to the PRAKTICA L, but has in addition a built-in photoelectric exposure meter (outside measuring). In view of the increasing demand for colour film with its somewhat limited exposure latitude, such a space and time saving unit is appreciated. Exposure time and aperture are determined according to the film speed and the subject illumination and is transferred to camera and lens.
