What are the trigger voltages of some Olympus (and other) flashes?
I just measured several of my flash units for their trigger voltage. It wasn’t difficult; had to use a paperclip on one or two to probe the side contact. Plus (+) on all of them is on the center contact: T-20: ~6 Volts T-32: ~12 Volts Sunpak 383 (new): ~7 Volts Metz 40MZ-3i w/SCA 321: ~5 Volts Metz 40MZ-3i w/SCA 301: ~5 Volts Sunpak 140: ~210 Volts Rollei E19BC: ~150 Volts The Sunpak 140 is an older model number (replaced by 141 ?) and the Rollei E19BC is even older. I use them on the Contax IIIa and Rollei 35, both of which are mechanical, including the flash trigger mechanisms. Hmmmm, guess I shouldn’t use either of them on the OM-2S or OM-4!
