Thanks for the link.

 

I got the lens today, but didn't have time to try it. Just ran the quick decentering test, and it passed.

 

For what concerns the adapter, at the moment I'm going to use the same I'm using for the Trioplan. For convenience, though, it probably makes sense to buy another.

 

Do you think a lens hood would make sense? The front element is about 1.5cm recessed... Today there was no sun so I couldn't try flare resistance; but a quick test done at home with an artificial light seemed to show that with a light source just out of the frame there is quite a few contrast reduction; and shielding with my hand improved things.
