Do not go ... there's not !!!

That was the invention of the century for me.
I've used these little helpers at a concert. By means of an adapter I could on my little Sony CX 730 this hot shoe adapter for "1/4" to attach an additional audio recording device, the Olympus LS-10 to set up, for example. That was perfect.
Thus I had the original sound of the camera and manually set the tone Olympus audio recorder ... was truly worth it. Soon I will join my little cam on a great camcorder, so to speak, as a biplane, through these little helpers, so with a Cam the shot and with the other take the detailed photos. Interesting variant when filming alone.
