My camera is a Cannon GL2 ($1500-$3000 depending) (I bought mine used from River Valley Game Calls where I pro staff and have used this camera for years, they upgraded to HD) and I bought the fluid head for on the tree arm from B&H Photo online store. $118.00 It's also where I buy my miniDV tapes etc..

My camera came with the Mic adapters:

I picked up some wireless mics that I haven't put to use when hunting by myself. They were more purchased for turkey hunting or when I'm serious with another shooter. :
