Quickest set up
 

I have the EX1 and am looking into either the Letus or Brevis. I will be shooting a documentary fairly soon and am wondering which of these adapters has the edge in terms of being the easiest to assemble on the fly. From the sounds of it, the image quality is comparable and portability is more important to me. Not run and gun exactly, mostly quick set ups for exterior shots. Are there other adapters in this price range that would fit the bill?
