Technical data

3. To activate the self-timer, push the self-timer start lover in the direction of
the arrow. The self-timer will then trip the shutter at a delayed action of
approximately 7 to 10 seconds.
· When using the self-timer to trip the shutter, slide the rubber eye-cup
mount upward as illustrated to prevent light from entering through the
viewfinder eyepiece. By thus shielding the viewfinder eyepiece, exposure
inaccuracy due to light filtering in from the eyepiece can be prevented
effectively.
· In case the film wind is incomplete, the self-timer will activate when the
self-timer start lever is pushed in the direction of the arrow but it will not trip
the shutter. In such a case, give the film advance a complete wind and reset
the self-timer lever.
· In case you decide not to use the self-timer after setting the lever in the
direction of the arrow, simply return the lever to its original position.
· The shutter can be released in the normal manner by pressing the magnetic
release even when the self-timer lever is set at the charged position.
DEPTH-OF-FIELD PREVIEW BUTTON/MIRROR LOCK
Depth-of-Field Preview Button
Although the viewfinder of your CONTAX RTS always provides viewing at
all aperture, depression of this button stops down the lens to the preselected
aperture, thus enabling depth-of-field preview.
Avoid tripping the shutter while depressing the depth-of-field preview button
because it will cause exposure inaccuracy.
Mirror Lock
In photomicrography and extreme close-up photography, better results can
be obtained by making exposure with the deflection mirror locked in flip-up
position.
