Sennheiser ME66

The Sennheiser ME66 works well, is fantastic at picking up sound. If using outdoors a windsock is a must! Boom operation is the best form of use, but can be mounted on top of camera also. Some packages come with a cute little brush to clean the windsock with. Our one lasted about 3 years with minimal problems (except it sometimes worked with battery off and sometimes wouldn't, but i imagine if we'd bothered to look in the manual we might have solved that), but went kaputte recently.
