It can ***if*** the RAF file is uploaded to Creative Cloud first and then added in PS Touch from there. (And only then your limited to just importing the RAF image; there isn't any RAW editing like in Camera Raw or Lightroom. Still handy though as you won't have to save in another image file format.)
ON EDIT: I'm assuming supported RAF/RAW file formats here; Adobe constantly updates their flagship products to support new cameras. Give it a shot anyway.
