1st, I want to say this forum is great. Loads of info. Learning allot. I have a question about mic's. I just purchased the HMC150. Doing some test shots to get used to it. I found that when zooming, the mechanism sound gets recorded. Presume due to where the mic is located. I come from years of consumer cams, my last being a Sony SR11, but don't know anything about external mics. If I buy an attached mic that mounts on the unit, will it still record the mechanism sound? Can someone recommend a decent mic that won't break the bank? B&H has 2 listed but the panny one is a bit expensive. Appreciate any help.
