Backscatter TTL Trigger not working anymore on my Sony A7R5

[Susa]

Hi all,

 

7 days ahead to my trip to Anilao, I tested my new BS trigger with my Sony A7R5 (connected and disconnected  with backscatter HF flash) again (I did it before 4 weeks, and it works all fine), but now it doesn't.

 

The diode is not showing any light. It doesn't work with remoteflash setting on or off. The trigger akku is full, the green light blinking 5 times and then the bluelight is blinkling, Sony setup is on fillflash, M, and like writen, remoteflash on and off 

 

Am I doing something wrong? Does anybody here have the same problem. I think I got some of the first BS was selling. 

 

Many thanks, I'm a little desperate since this is so short before my trip to the Phillies. 😞

First step is to observe the LEDs to see if they are flashing when you press the shutter button.  Check that your hotshoe mount is seated properly as well.  Closely inspect the hotshoe, on Sony they have rather fine pins that are easily damaged, see if one of them is bent. 

 

Which model do you have the universal with the plug-in LEDs or the Nauticam model?  If it's the universal one have you tried swapping between the single and double LED cables?

 

Have you tried it with wireless mode on and off?

Thanks! Yes, I tried with wireless on/off, and a normal Godox flash works, so I think camera is working. Now I will get a pair new cables from my dealer. This is the next test. I have the single universal  configuration in an Isotta house, and the thing is, it worked before! Unfortunately I do not have the double version.

When you say it works with a godox flash you mean a godox in the camera hotshoe?

 

The problem with the hotshoes on Sony flashes is the hotshoe connector which is on your flash trigger this one and it's the pins I have indicated that can have problems:

Hi meanwhile everything works! The problem was the camera! After resetting it and configure step by step, testing with a Godox flash, it works. Now unfortunately I have the problem that my Backscatter Dual Bulk Head adapter doesn't fit on my Isotta housing, I think the cutout for the hole part diameter is too small, so I cant be completely screwed in. It leaks :-(.

I'm not sure I understand the issue with the bulkhead, does the little rim around the M16 holes prevent you screwing it all the way in.  One option might be an M24-M16 adapter if you find one compatable with the M24 hole and the bulkhead.

 

Otherwise you could use the inbuilt fibre optic ports of the housing for one strobe as a stop gap until you could get a suitable adapter to use the bulkhead or perhaps you could get a twin LED cable to route to the two fibre optic ports built into the housing.

Thanks again, I ordered exactly a 24-16 adapter, and another adapter for M16 (picture) to be on the save side,  if it arrives tomorrow , my problem should  be solved and I could use the BS trigger in Anilao 🙂
