I have an a6300 and recently purchased a HLV-F43M for added flexibility, and enjoy it. I thought that this flash could be used off-camera and be triggered by the a6300's built-in flash. I tried the procedure in the flash operating instruction book, but could not get the camera and flash to pair up and show the "WL" icon. Is my assumption about compatibility wrong? Do I need an adapter/trigger? Or do I just not know how to follow instructions? Is there a tutorial you know of? All help appreciated.
