This is an add-on that I wrote for blender 2.69+

After installing it adds 2 options to the Add> Armature menu.
Dolly Camera Rig
Crane Camera Rig

I'm currently in the process of trying to get it included in the official release of blender.
But in the mean time it can be downloaded from here:
raw.github.com/waylow/Add_Camera_Rigs/master/rigging_camerarigs.py

If you find any bugs - please message me.
