Schneider Apo Digitar 24mm 5.6 XL - Quality query on CFV 100C

[HasselCam]

Has anyone tried the Schneider Apo Digitar 24mm 5.6 XL with centre filter with the CFV 100C?

I'm looking for something wide to use with the Cambo Actus and have heard some reports of issues with the schneiders.

Also.. is the centre filter necessary or is it poss to use this lens and making adjustments in LR or Phocus?

Your responses greatly received.
