Direct metering of the flash exposures at the film plane is possible with the combination of the TLA-20 Auto Flash and either the Contax 139 Quartz, Contax 137 MA Quartz, or Contax RTS II Quartz. Attached directly to the camera body and set for "AUTO" operation, the TLA-20 works completely through the SPD metering systems of either camera for complete control of flash exposure, at any aperture, because the camera meters flash intensity during exposure and cuts off flash output precisely as exposure values become perfect. And with the optional TLA-20 Extension Cord 100, the flash unit can be operated from any position, a fantastic advantage for bounce-flash techniques, close-ups, copying and other creative possibilities.
