Braun VarioZoom 340 Flash: "extern" mode?

Hello all,

some time ago I bought a pair of Pentax SPIIs at a flea market. Among other stuff, they came with a Braun VarioZoom 340 SCA Flash. It has the "SCA 100" foot that seems not to be dedicated to any specific camera. This flash has 4 operational modes: "manual" (always fires at full power) "4" and "8" (for automatic power setting at f/4 and f/8) and "extern". The manual I found online doesn't seem to contain much useful information about this last mode, other than that it "is used only with cameras that meter off the film plane during exposure". Does anybody happen to know how this mode works and if/how it would work with an LX?

Cheers, Le Chuck

Why don't you give it a test: attach the flash to the LX, set at f/16, 100 ASA, fire a shot. Change to f/1.4, 400 ASA, fire another shot. Even without a flash meter, you should be able to tell if the flash strobe in the second shot is shorter.

Well, I probably should have mentioned: I don't have an LX yet
