Thanks, Jason, for your response. My flash works well. I've used it for a long time with my other camera body (a 139Q) and never failed. When I shot the RTS3 the flash fires.
I've tested that with MM and AE lenses.
I've written here because it's strange for me using this kind of feature only switching a lever, without pressing after any button.
