"High quality for the price. Smaller shotgun microphone. Actually the radius (21mm) is smaller than the mic clamp on the XA10. It does come with two O-rings to increase the diameter but they don't work with the XA10 clamps. You'll need to rap a piece of foam around it unless you can find an adapter sleeve of some sort."
"Compact cable for the shotgun mic. Note: a right angle male XLR end would be ideal for plugging into the camera end BUT the typical right angle XLR plug has the pins situated so the right angle would direct the cord UP on this camera when you would want it to angle down. So unless you have an end that rotates, best get a straight connector for the camera end."
