What version of FCP are you running? Only FCP 7.0.3 can deal with footage from that camera in Log and Transfer...and only if you have the plugin from Sony (which they might no longer make available).
BUT, as Meg pointed out, EditReady will be your best bet. The company also made ClipWrap2...and that might work if your OS is older, as EditReady needs a current OS. ClipWrap2 was ready to handle the NX footage before FCP was. I was working on a pilot for a show shot with that camera, and FCP couldn't deal with it. I emailed the developer of CLipWrap2 and sent test footage...and got an update two days later and it worked! FCP support came months later. But now that FCP 7 is no longer being developed, many camera makers have removed the plugins for that version...so you might need ClipWrap2 for this.
