Not sure where f16 came in WRT the Contax-mount Hologon, but that lens is 
f8, that's all, fixed, so f8 is both the maximum and minimum aperture of 
the Contax mount Hologon lens.

The Heliar is more conventional, with a maximum aperture of f4.5, and 
f-stops down to f22.

> You can meter on the Heliar and not the Contax

Yes, that way round.
