Flash Trigger Voltage Limits for M6TTL and CLE

[blackdot]

I have a few vintage flashes that have very high trigger voltages, and I’m a bit hesitant to use them on either of these two cameras without confirming they won’t fry the TTL circuits. Does anyone know the trigger voltage limits for the M6TTL and Minolta CLE?

I don't but others will .  def don't try it (especially CLE) without knowing for sure as I did read of people cooking their electronics

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

I wish I can help, nothing in my archives.

Which one was for CLE, voltage I don't know.

Minolta voltages in various strobes are very variable, like here from 1.7V to 297V:

Minolta	Auto 22	No	240.1 measured by Derek Woodlands
	Auto 25	No	210V measured by Steven Ferland
	Auto 28	No	200V according to Wes Quigley, only 43V from Gene West
	Auto 32	No	192V measured by Rob Babcock
	Auto 128	No	297V according to Ed White
	132PX	Your Call/No	20-30V per Minolta Customer Service, courtesy Karen Wetterling
	132X	Yes	2.2V per SJ Chandler
	Auto200X	Yes(?)	2.9V per Brian Klug,, but 6.7-6.9V per W.S. Ryu
	Auto280PX	Yes	1.8V (!) per Richard Crow
	Auto320X	Your call	10.44V, measured by Thomas Whitehurst, but varying 5.4-8.9V according to Ian Hamilton
	Auto360PX	Yes	5.24V per “Nahau”
	1800AF	Yes	A mere 1.88V per Lieven Blancke & Mark Ball
	2800AF	Yes	1.74V, per Manuel V. Galang, 1.65V from Jeroen Haringman
	3500xi	Yes	1.88V, also tested by Manuel V. Galang, who reported good manual success with his G2
	3600HSD	Yes	3.5V, per Toney Hall
	4000 AF	Yes	1.85-2.5V, per Mark Vinsen
	5400HS	Yes	4.7V, measured by Hardeep

I don't know the limits, but why risk it? The cameras are expensive and their metering circuits aren't fully repairable, while flashguns are cheap, including good models known to have low trigger voltages (as in the link above).

Why risk it indeed - I haven't used flash in 40 years. When I needed to do portraits for an organization about 10 years ago, I set up LED flood panels - easy to see the effects and set exposure.

Thanks. I have this list bookmarked as well.

I have an old, really old Vivitar 285. Do NOT use on any modern SLR/DSLR with electronics inside. It will melt them.. A Braun Studio flash melted my M3 contacts!

Sold flash! Personally I hate flash..
