Worked with my Canon 7D out of the box. There is no way of controlling the level of sound (restriction of the Canon 7D) About did not aim it poses Any problems. The wind problem (the reason I purchased this it) is taken care of only Partially, I would-have appreciated a switchable low pass filter to attenuate the noise of the wind. There is a switch to select 90 degrees or 120 degrees sensitiveness, I Recognize there is a difference, it aims Has No added value for me. I can recommend it for traveling and family movie work.
