If you are looking for a good on-camera microphone, Azden has a new option, the SGM-250CX Professional Compact Cine Mic. What sets this mic apart are some pro features, like a full-size XLR plug and Phantom power. But here is my full review.
So, again, I really like that the Azden SGM-250CX has the XLR connection, Phantom power, and that you can easily remove the shock mount. It attaches to the top of the camera via the standard hot/cold shoe, or you can attach it to a boom.
