What lens would you use on a BMPCC to match Signature Primes?

[Markus A Ljungberg]

Hi all, would love some suggestions on lenses 

Just wrapped a feature that we shot on Venice 2 and Signature Primes. I'm planning to shoot some additional bits consisting of exteriors of buildings, details inside a church, some landscapes etc. The budget is pretty much spent so it will be me and my BMPCC 6k (Modded to PL mount). I'm now looking at lens options. Just curios, what would you pick for a good match? It should be something fairly clean so I'm considering UPs or potentially Sigma FF High Speed or Sigma FF Classics.

Looking forward to hear your thoughts, thanks
