Hi There.

Looking at the photo you have on the other post, I would say your problem is the YS01 is nos being triggered by the internal flash. It looks like the light from the internal is filtering from the housing and lighting wall.

If that is the case. make sure the fibre optic cable is properly connected and is not broken at any point. Try to take a photo of the hole system against a mirror. if your strobe is firing you will see it in the shot.

Make sure the YS01 is in the right mode. if you are shooting in P, A or A modes, the strobe has to be set to pre-flash (2 lighting bolts) or TTL. On M mode, the flash has to be set to No pre-flash (1 light bolt)

The TTL mode on the YS01 is known for being very unreliable and have the tendency to massively overexpose however I haven't had a chance to test it with the RX100

The YS-01 works perfectly fine with the RX100 and the information previously posted is incorrect you cannot trigger the YS-01 in no preflash mode as the RX100 always fires a preflash So your rx100 has to be set to fill flash and your YS-01 to TTL Don't make the mistake of pointing the strobe to the flash in ttl mode as that will just end up with an Underexposed picture If you want to test is the strobe fires put it in front of the camera in Pre-flash mode if you want to check ttl you will need to aim the strobe at the subject
