So I am new to the universe of cameras with equipment. Currently we have a green screen in our studio and acquired a Sony a6300 when it launched. The camera is amazing, especially since it supports 4k output. We bought the Stereo microphone from Sony, and in a sound proof room it still has a static vibration sound. My question is, what is a good affordable microphone to use while filming. We're not going high-end until we see a need, for now we're testing this setup to see how we can scale. Thanks!
