Commander in Leica M9

Hello everyone:

my name is Maurizio and I'm Italian. This is my first post here although I registered years ago.

I'm writing because I have a problem with a flash on my Leica M9, which I can not solve.

I have a nikon SB-900 flash that works in manual regularly on the M9. Now I have bought a Debao SU-800 remote commander but the signal does not reach the flash.
(Debao work normally with my nikon camera). (I know it's shameful to apply a Debao in a leica m9).

Naturally I set the same "communication channel" and "group name" in commander and remote flash. When I shoot the remote flash does not turn on

One more thing: When the test lamp, in the SU-800, is red, I press the test button, and the flash turns on but after a couple of seconds.

Can someone help me solve this problem? Thank you very much for helping.
(I apologize for my bad english)

Contact spray?

What’s the shutter speed? If it’s too high the M9 just doesn’t apply power to the shoe

Hi Mauri; please check if the flash is set as SLAVE and not MASTER; if you use a remote control this might be the cause.

Also, as antigallican suggested, check the shutter speed that for the M9 is 180 or slower.

 

Last but not least, check if the flash is properly camera installed

 

Best

Thanks so much for the answers.I can try with the spray. The shutter speed is 180 (flash simbol in the shutter speed dial) and the flash is setted as slave. I always use remote flash with my nikon camera and I do not understand why it does not work with Leica.

I'm not sure if here any non-Leica camera which support Leica M Flash protocol, control, firmware. Most likely your flash is fired if on camera by single centrer contact, which is nothing but contact closure. And then does it in auto mode, with its own metering.

I guess, commander needs more than one contact communications.

Thanks for the reply. I will try to understand how to do it
