Well, the distance to the objects can be taken "for all practical
purposes" to be infinity, so the object's parallax for the two images
between the two eyes (even slightly enhanced by the bino distance) would
be very close to 0, so I agree on this.

I am still wondering why do I get the distinct 3D sensation and what
causes it. Perhaps sphericity of field in low quality achromats?
