I have tried to make a search for SONY ECM670 in this forum but can't find any post about this microphone. The size looks good for using it as an on camera microphone. Any experience?
I had to edit this post because that mic used to cost more... I checked my info at B&H and it's listed at $299 with some kind of rebate... Hopefully it's a good mic at that price.
You're right in the range of the AT897 at that price... so I'd compare those two before you buy.
