+1. Been using lenses from the early 1990s on an AFI with Leaf back, work fine. The 180 is a great lens, have no experience with the other 2. But I don't think an AFI back will go on a 6008?.. Sinar made backs with adapters, as did Imacon (Hassy), and there was a Phase back (DP20) that would go on a 6008, but AFAIK no Leaf fitting. Check with Eric at Rolleiflex.us
