Toward the lower end of your range are the Rode NTG1 and NTG2. The latter has an internal powering (AA battery) option. If only they'd put an on/off switch on it.
Yeah im looking at an on camera mic.
I shoot inside and out and mostly shoot bmx.
Panasonic do a mic150 which is specific for the HMC150, do you think this would ok or would i be better off spending a little more and getting a Rode NTG-1 or NTG-2?
