A:AnswerDo these in order
1 ) put new batteries in flash
2) make sure camera has functional batteries. Can still be low as long as they can turn camera on. Recharged, Fresh the best. New/RECHARGED.
3) turn camera on.
4) turn flash on
5) fire flash
Hopefully it works now
A:AnswerI don’t think this will work on-camera with a Sony mirrorless. The Sony cameras have a proprietary hot shoe which is different than any other manufacturer. The universal identification of this flash is more that it works with both Nikon and Canon cameras, DSLR in particular.
