What mic is better for...
 

I all,

Looking for 2 advices.

I'm going to shoot a long corporate video with a lot of outdoors in the country.
1- I need the ambience sound of the car in a distant road, the birds in the trees, etc., etc.
2- I also need a mic for the interviws. I have a wireless, but want to buy a shotgun. To start working properly !

My camera is a Z1.

I've looked at the AT987, AT4073a and the MKH416.
What's better for me for each application ?
Maybe none of these is appropriated for ambiance sound ? What advice?

Does the Stereo Shotgun's do provide a nice stereo ambience, or is better to have a decent "mono" mic ?

I'm also lookig for a "proper" support for the mic to adapt on the Z1.
I remenber to see a nice one but can't find that post. I also remenber it was not cheap... ... ...


Thanks
Carlos Manuel
