Focussing on the virtual image created by a dome port either requires a lens which will focus close, or a supplementary close up lens on the camera lens. B&W seemed to be better than plano-convex custom dioptres I had made in New Zealand. For experiments with over/under pictures I bought B&W lenses and had them cut in half. I can provide pictures if you are interested in any individual lenses, or make me an offer for the lot!
