mburnham Posted April 20, 2012 Share #1 Â Posted April 20, 2012 Advertisement (gone after registration) Hi all, I am looking for advice. I used the M9 with studio flash and had no problems, then subsequently gave my hot shoe to my daughter. Bought myself another, connected up the lights, fitted the shoe and the cable, and NO FLASH! Test button on hot shoe fires the flash, but the camera doesn't Bought myself yet another hot shoe (simple, old fashioned) and tried again but still no flash. Unless anybody knows different I can only assume that a connection within the camera has failed. Rather inconvenient for my studio work! Does anybody have any suggestions?

meino Posted April 20, 2012 Share #2  Posted April 20, 2012 What timer setting did you use, the M9 won't trigger a flash with speeds > 1/180. Also the A setting won't trigger simple flashes  regards Meino Link to post Share on other sites More sharing options...
mburnham Posted April 20, 2012 Author Share #3 Â Posted April 20, 2012 I'm pretty certain I was on 1/125, but I didn't think about the setting feature. That will not have changed, so I will check it. Thanks for that idea Regards Mike Link to post Share on other sites More sharing options...
mburnham Posted April 21, 2012 Author Share #4  Posted April 21, 2012 If I knew my camera better, I would have realised that it can't be on 1/125 & A at the same time  So same question remains. Link to post Share on other sites More sharing options...
giordano Posted April 21, 2012 Share #5 Â Posted April 21, 2012 Try another, ordinary flashgun on the Leica, and try the connector foot on another camera's hot shoe. That will tell you with certainty what's happening. Â Remember that it's possible for an old-fashioned flashgun or studio strobe with a high trigger voltage to fry the synch circuit of an electronic camera. There doesn't seem to be any authoritative statement on the maximum voltage for which the digital Ms are designed, but the highest value that I've ever seen suggested is 240v and some obsolete units exceed this. Many cameras can't tolerate even this much. Â Another possibility is that the "simple, old fashioned" hot foot is wired up with the opposite polarity to the one you gave away; IIRC most electronic cameras won't trigger a flash unless the centre connector is +ve.

mburnham Posted April 22, 2012 Author Share #6 Â Posted April 22, 2012 Many thanks for that advice. Â I connected up a flashgun to the camera and we had operation! So I know that the camera unit is good, now just need to check the hotshot on another camera. I think this question is now closed. Many thanks for assistance.

I wish people would read the M9 FAQ before saying things that are clearly incorrect.... 600 Volts for the M8/9.... http://www.l-camera-forum.com/leica-forum/leica-m9-forum/130720-m9-faqs-frequently-asked-questions-answers.html#post1536447 Link to post Share on other sites More sharing options...
