Over the next week I will be shooting as a stills photographer at a local movie shooting. I have been talking to the director, and we are both concerned about the shutter noise being picked up by the boom mics. The simple solution for shooting outside is using my 70-200 2.8is and staying far back, but for the inside shots, I need a way to quiet my camera. I have looked all over for a 'sound blimp' for my Canon XTi (400d) but have found nothing, any ideas? My budget is $150.
