I'm using the Kipon T/S adapter on my Nex cameras with an 18mm C/Y Distagon leitaxed to Nikon F, and a 25/2.8 ZF.1 Distagon and I'm getting great results.
For reference I don't use T/S on my D800 (Rokinon on backorder) but I do use the 17mm TSE, and adapted 35mm TS FD and/or Pentax 645, and the 90mm TSE on my 1ds3
I would say choose your camera format 1st, then T/S solution.
