1949 FASTAX VIEW FINDER 601 focusing and study of subject detail without the use of auxiliary lighting during this operation. This is an important advantage where special lighting is to be used during the actual filming and where such light (perhaps because of its intensity, duration, or other special characteristics) may not be suitable for this purpose. Furthermore, heat from lights (even at reduced voltage) may affect the operation of certain subjects containing delicate materials or mechanisms. Eliminating auxiliary lighting during focusing and composing has proved to be a definite help in such cases. The 10-power view finder permits study of detail in distant objects since it acts as a telescope when used with the taking lens. For example, with a 10-inch telephoto lens the combined system acts as a 10power telescope; with a 4-inch lens, it is a 4-power telescope. The rectangular frame on the reticle represents the field of view of the camera. Because of a slight cutoff by the compensating prism, the entire vertical field is not seen in the finder except by slight rotation of this prism either side of its central orientation. In addition to the seven lenses ranging from the 35-mm //2 to the 1 5-inch //5. 6 telephoto, a new 1-inch //2. 5 lens has been developed for special work where a wider field (horizontal field equals 22 degrees) is needed. A special 30-inch //ll telephoto lens is also in the process of design.
