顺手把我从网上找到的这老古董的一些特点介绍一下，对不起，只找到英文的：
ZENIT-122 is a 35-mm single lens reflex camera intended for taking various amateur pictures on black-and-white and color films. It can be used for special kinds of photography as well, such as copying, taking close-up pictures of small-size objects at short distances (ultra-close-up photography), taking pictures with the help of a microscope (photomicrography), etc.
The camera accepts interchangeable lenses with M42x1 screw fittings and mechanical back focal distance of 45.5 mm.
The following features are remarkable with the camera:
semi-automatic exposure meter operating through the lens (TTL system) provides for correct exposure setting when taking pictures with the standard lens as well as with interchangeable lenses, light filters, supplementary lenses, extension tubes;
light-emitting diodes in the viewfinder, indicating correct exposure setting, can be clearly seen both with the diaphragm fully open and stopped down;
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 down for the moment of shutter operation;
fully open diaphragm ensures maximum brightness of the image in the view-finder which is very important for viewing and focusing;
composite focusing device provides excellent image sharpness in various conditions of shooting;
speedy exposure setting, simplified film loading procedure and frame counter automatically re-setting to "0" upon pressing the film rewind button reduce the time required for preparing the camera for picture taking;
built-in self-timer enables you to take picture of yourselves among your friends or to make a self-portrait;
secret lock of the back door interlocked with the film rewind knob provides for reliable locking of the back door and convenient unloading of the camera;
flash unit connector socket and hot-shoe enable to use flash units both with cable and cableless connection;
shutter disengaging bush of stay-put type simplifies the film rewind procedure;
