HI Wilbur, My guess it's small feature culling the small spheres when the model extents are larger which causes the initial viewpoint to be further away.
You can swtich off small feature culling via camera->setCullingMask( camera->getCullingMask() & ~osg::CullingSet::SMALL_FEATURE_CULLING); For other related settings see the osg::CullingSet class that osg::Camera inherits from.
