Summary: My wife bought me a a Sony tripod years ago to work with my Sony still camera. However, it had a built-in remote control arm which wouldn't plug into my new Canon Vixia HD vidoe camera. This adapter fit the bill and saved me from haivng to purchase a different tripod. Plugged into the shoe onto of the camera, I was able to plug the cable from the tripod remote into it and all the controls worked!
Summary: Not happy that this feature isn't standard in my camcorder (Canon Vixia HF M400). Not happy that I don't have any available shoe slot anymore since this unit sits in the top shoe mount. With my LANC Remote control, I am able to do everything that I expect, except take a still photo with my camcorder. Its supposed to work, but it doesn't. I still give 5 stars because its does the LANC capability well.
Not a worthwhile investment. it didn't work for me.

Summary: I'd hoped this would enable my wired remote control (LANC) to function with a tripod. It didn't work at all as intended...the Canon Vixia HF camera repeatedly cycled on and off...rendering the Remote and the camera useless. I returned the adapter for a full refund, so I must praise the refund process as being worthwhile and valuable. Can't say that for the Canon Remote Control Adapter however. Not at all like other Canon products I have.
Summary: This is rediculously over priced. Installs easily to the camcorder, but is useless unless you buy the way overpriced control that is the only one that talks to it. vivitar control heads do not work with this unit. Even though the interface protocol is suppose to be standard.
Summary: This adapter is only for the Remote Control. The Remote control is very expensive if you want to be able to turn the camera on/off. The supplied remote control that comes with mycamera is wireless and can do most of what you would do through this adapter. But the wireless does not turn the camera on/off. Think about the cost/benefit.
Summary: ...if either you have a compatible camera or you try a workaround to fix the "buzz"... I first ordered this without knowing the "official" compatibility offerings... I have a Canon HF-S100. Well, the "audio-buzz" is definitely there. I have the Rode VideoMic and when the 2 are connected to the camera you can hear the buzz - although it's not over-powering, it is enough to annoy. It seems to be a ground loop problem.
Summary: At first this worked with only the HF11 after I bought my HF10, so I was out of consideration. But then rumors started. It worked in HF10's with noise on the audio line (the external input, which I use all the time with radio mics and the cam-3 AZDEN CAM-3 On-Camcorder Mini Audio Mixer So I connected up a senn ENG100P3 and turned down the output on the receiver then turned up the input on the HF-10 camera. NO noise while running the lanc signals - none at all.
Summary: The RA-V1 is not specifically advertised for my camcorder (Canon HF S10) but works well for me. The ability to start and stop recording as well as control the zoom is available via my LANC controller using this adapter.
