Description
The camera is provided with a semi-automatic exposure meter operating through the lens (TTL) a self-timer and is synchronized for flash lamp operation. It accepts interchangeable lenses provided, with mounting thread of M42×1 and back focal distance of 45.5 mm.
ZENIT-TTL can be used for special kinds of photography such as reproduction works with the help of extension tubes, taking close-up pictures of small subjects at close distance (macrophotography), taking pictures with the help of a microscope (microphotography) and so on.
ZENIT-TTL camera has the following advantages:
- semi-automatic TTL exposure meter provides for correct exposure setting when taking pictures with the standard lens as well as with interchangeable lenses and extension tubes;
- instant return mirror ensures continuous viewing of a subject before and after exposure;
- high speed lens is provided with a pre-set diaphragm mechanism which automatically closes the diaphragm at the moment of the shutter operation (“A” mode); manual operation of the diaphragm is provided as well (“M” mode);
- fully open diaphragm ensures maximum brightness of the image seen in the viewfinder; this fact is very important at the moment of viewing and focusing;
- focusing can be done both by a microraster or a ground glass;
- speedy exposure setting, the system of simplified film loading, rewinding of exposed film with the shutter disengaging bush in locked position — all these features cut down the time necessary for preparing the camera for operation.
