Camera setup script finished..enjoy
here's a script I've been working on. It'll make camera animation alot easier. Some people have helped me create it when I got stuck on the coding, so if you like it use it.

What it will do is create a number of cameras with a name ou provide and create group transforms so you can animate easily for each transform node, as I lock out the non editable/animatable transforms you don't want..

here's the code...

//This script is inspired from Eric Hanson's Digital Sets DVd's
//Many thanks to alot of folks on cgtalk
//especially Andrew, aka Westimad and Robert Bateman
//Please distribute this script freely
global proc Procam()
{
//variable creation here
string $grp1 = "XYZ_Trans";
string $grp2 = "YRot_Pan";
string $grp3 = "XRot_Tilt";
string $grp4 = "ZRot_Roll";
string $winName = "ProCam";
string $camnode = "1NodeCam";
string $camnode2 = "2NodeCam";
string $camnode3 = "3NodeCam";

//window check
if(`window -exists $winName`)

windowPref -remove $winName;

//window creation Layout here

string $checka = `checkBox -l $camnode onenode`;
string $checkb = `checkBox -l $camnode2 twonode`;

string $butn = `button -label "Create Camera" -c "Values" mybutton`;

//embedded form layout here
