New lens for 2019, what would you like?

A 50mm real Sonnar lens for SLRs!

Very kind of you to offer, I'd like something for astrophotography so ultra wide, sharp & fast please. PK mount preferred as I can adapt that to all my digital cameras
The lenses I buy myself never quite meet these requirements, with ultra compact lenses being the majority of recent additions (rangefinder lenses for the last two).
