The Summicron (collapsible) has a soft front element - I've seen many, many examples with lots of scratches.
I think the Elmar has soft coating too, but I'm not sure.
In my neck of the woods, many lenses I come across are hazy. Even if a lens can be cleaned, dealers just don't want to pay to have it done. I'm not sure if that's a worldwide trend, or just here in Japan. At any rate, in my experience generally the older the lens, the harder it is to find a clean example.
