Just check the type for 'op' to make sure it's a camera than cast it:
if (!op->IsInstanceOf(Ocamera)) // return or something
CameraObject* cam = static_cast<CameraObject*>(op);
// Voila, BaseObject op is now a camera.

Thanks for the Info!
Wow, that sounds pretty easy. So after that I use "cam" as the camera object, and it has all methods and properties of a BaseCamera (or a RayCamera)?

Yes, it has all methods of the CameraObject class (there is no BaseCamera object).

Hm...
I get an error in this line:CameraObject* cam = static_cast<CameraObject*>(op);Error message:
error C2065: 'MyCam': nichtdeklarierter BezeichnerI thought "CameraObject* cam" IS the declaration?
Thanks again,

Where is 'MyCam' coming from? Maybe you have it undeclared but used elsewhere? If the cast gives you trouble, just use the old C-style cast instead:
CameraObject* cam = (CameraObject* )op;

It works now... but another problem:
I don't find a parameter for setting the "Target Distance" of the camera. How can I access thos depth parameters?Thanks again in advance!

Target what? Most cameras use a direction vector (eye vector or whatnot) to point the camera which is based on the camera's rotation - there isn't an explicit target and thus no 'target distance'.
Cameras in C4D are only explicitly targeted when using a Target tag and you could do the simple math of determining the distance from the camera's global origin to the target's global origin in these cases.

Yes, I know that. I am writing a plugin that - besides other features - also does targeting. I won't use the normal target expression tag. My target function already works, that's not the problem.
Anyway, a camera has an attribute "Target distance" which can be found in the depth attributes (used for setting the focus of the DOF). The normal target expression tag can adjust the target distance attribute, I want to do that too, since it would be a very important function in my plugin.

Hey Jack,
look up the ID in the Ocamera.h (or .res) resource file (you find this and also files for all other objects,tags,nodes,videoposts in ..c4dfolder\resource\res\description\)and then simply use cam->GetDataInstance()->SetReal().
The ID for targetdistance is CAMERAOBJECT_TARGETDISTANCE

Btw., the functions in the CameraObject class are only there for convenience, so to make your life easier, but you can still set all the parameters via their corresponding IDs within the BaseContainer directly. Just as a side note as I think that was the initial problem you had...
Keep going.

That may be one of the best tips, thanks Samir! I'll try that.
Hope to see you in Cologne, btw
