Technical data

Your CONTAX RTS features fully automatic through-the-lens electronic

exposure control.

By simply presetting the film speed and lens aperture, its highly

sophisticated electronic circuit functions to vary the shutter speed

continuously and automatically according to the subject brightness, thus

ensuring correct exposure under any light condition.

Besides fully automatic exposure control through aperture preselection,

your CONTAX RTS provides semi-automatic exposure control through

preselection of the shutter speed.

Automatic exposure through aperture preselection

1. Turn the shutter control dial and align the 'AUTO' setting with the index

on the camera top.

When thus adjusted, the green shutter speed pointer in the viewfinder will

overlap the 'A' setting.

· Make sure the exposure compensation pointer is aligned with 'X1 '.

2. Preselect the lens aperture. Turn the aperture ring on the lens barrel and

align the required f-number with the index. The preselected aperture will be

displayed in the viewfinder in green figure. Refer to the table for

approximate aperture setting under different light conditions.
