Draw a triangle. At 80mm the width at the wide spot is so large. The more extension the wider the wide spot is.
Yes, but I think the same effect is achieved by the focusing bellows.

I'll have to see about a 105mm lens. The 135mm El-Nikkor lens I got was such a steal -- mislabeled Ebay listing, went for $9.

I guess I can resell it to help finance the 105mm.
