I understand that Pioneer 10 & 11's imaging photopolarimeters were different from cameras on later spacecraft. But I'm wondering what the "focal length" equivalent might have been. In other words, were the photopolarimeters "zoomed in" like a telescope, or did they behave like something closer to a 50mm "normal" lens on a modern camera? I realize this is probably comparing apples to oranges, but I was wondering how they worked in this respect.
