The lens opening controls the amount of light that will pass through the lens onto the light-sensitive film.
 Your Yashica MAT-EM with its Yashinon lens offers openings f / 3 5, 4,56,8,11,16, and 22.

Notice that the lower the number, the larger the opening F 3 5 is the largest opening, f 22 the smallest

The Shutter Speed controls the duration of the exposure. Shutter speeds on this camera with its fine Copal Shutter are 1, 1/2, 1/4, 1/8, 1/l5, 1/30, 1/60, 1/125, 1/250, 1/500 of a second and B. The 'B' setting is for taking pictures with an exposure longer than 1 second. Use a Tripod or Brace when using B. When you press the Shutter Release Button on the "B" setting the shutter stays open until you release pressure on the button.4www.butkus.org

It is advisable to set the shutter speed before you cock the shutter all times.


When you focus the camera on a subject there is a certain distance in front of and back of the subject within which other objects will also appear sharp. This is known as the " Depth-of-Field," and it varies with the lens aperture. The smaller the aperture, the greater the Depth-of-Field.

If the camera is focused at 10 meters and the lens aperture is f / 16, the Depth-of-Field {area in which all objects are sharp! is from about 5 meters to infinity.4www.butkus.org


Be sure to replace the lens Cap when your camera is not in use. Keep your camera away from dust and moisture. For cleaning the lens surface to remove dust or dirt, always wipe very lightly by using clean gauze or lens cleaning cloth. Do not wipe the lens with a dirty handkerchief. When you are not using your camera for a long period do not leave the shutter set.
