Camera export

Hi!

I'm trying to export cameras using the API,
i have 3 cameras in the scene, 2 are exported correclty
but the thirs one has wrong coordinates ,any idea ?

I use this to get translations coordinates :
MFnTransform transfo(parent);

pos.x = transfo.translation(MSpace::kObject).x;
pos.y = transfo.translation(MSpace::kObject).y;
pos.z = transfo.translation(MSpace::kObject).z;
