Help with my new YS-D2 strobes, from a desperate researcher in Mozambique in Lights, Strobes, and Lighting Technique Posted January 26 Hey all. Thanks so much to everyone that tried to help me problem solve. The problem is not going away and I cant seem to figure it out. It must be something with this particular model strobe and my canon camera which uses a flash trigger *see attached. Thanks for letting me know that the D2s are ultra sensitive. This is all that it could be. There is a strong white light being produced by the flash trigger on both sides of the trigger. The flash trigger works with the D1s. Also weird that the D2Js work and not the normal D2s. I wish I had known this before buying and shipping one of them all the way out to Mozambique during Corona times. They should come with a warning and hopefully stores can start letting people know that this might be a problem so that it doesnt happen to others. For now I will have to return to the D1s. Thanks everyone.
