To set the aperture, turn the aperture ring untilthe desired aperture settingis aligned with the aperture/distance scale index.

Whenthe settingis shiftedto a next largernumber(for example, from 125to 250), the exposure time is successively halved with each setting; conversely, when shifted a next smaller to number, exposure the time is successively with each setting.

When the end of the roll of film is reached it will not be possible to advance the film any further. lnstead of attempting to forcibly advance the film , check the exposure counter to see whether you have come to the end of the roll. Lf so, be sure to rewind the film into ifs cassette before removing it from the camera.

With the Contax 159MM, you can use the shutter control dial to select any one of three program modes, aperturepriority AE mode, and manual exposure mode to suit any photographic obiective. (Program AE Mode) In the Program mode, the cameraautomatically AE selects optimum the combination shutterspeedand of aperture settings correctexposure for according to lighting condition usingits pre-programmed by matching shutter speedand lensaperture settings.
