Python: Keying the focal length (Blender 2.75)

Hello Guys,

i am working on a addon for Blender.
One the i want to keyframe with this Addon is the focal length of the camera.

But i do have a problem with the parameter of the camera:

>>> bpy.context.object.keyframe_insert(data_path=“lens”, frame=bpy.context.scene.frame_current)
Traceback (most recent call last):
File “<blender_console>”, line 1, in <module>
TypeError: bpy_struct.keyframe_insert() property “lens” not found

This says that “lens” is not found. Looking into Graph Editor it says that the RNA Path is “lens”.

Does anyone know what the problem is?


Problem solved:‘lens’,frame=1)

The Data was missing :wink:
