sony Z5

I am connecting a Sony Z5 video camera to my MacBook Pro via firewire and thunderbolt converter and it knows there is a camera there but when I try and connect to it, it just says I need the codec in final cut pro in order to decompress the image format. I use Adobe Premiere instead and it seems bizarre that the ability of this software to work with any camera is dependent on what edit software I use! Has anyone else had this problem and has anyone found a solution (that is not buying final cut pro!).
