About a month ago I bought myself an Azden SMX-10 shotgun mic, it seems that in the filmmaking community this mic is the cheaper alternative to the Rode video mic. So far after some audio tests and using it in a couple interviews, in my opinion its a good run and gun microphone, without magic lantern and disabling the automatic gain it gives you audio that's just slightly better than the onboard mic. I will be getting the Sescom AGC cable soon so I can get some clean audio out of it and will probably do a test video.
