HI Igor, I believe you are getting your terms mixed up. Focal length is not something that varies for X and Y axis of camera, and an osg::Camera no GL camera don't have a concept of a focal length. If you are doing depth of field rendering technique then field of view would be relevant, but it really doesn't sound like this what you mean.
I can't work out what you mean given you use of terms is so confused. Robert.
