To be honest, I fail to comprehend Phase's marketing plan. anyone needing the tilt & shift capabilities of a view camera can just buy a 4x5" monorail on eBay. Good ones often sell for a few hundred. Add a Rodenstock Grandagon 90 mm or a Super angulon 90 from Schneider plus bits and pieces and you have a complete and nice system for less than the price of their 80 mm.
A Japanese seller frequently advertizes the Fuji GX 680 as complete set (film back, camera and a lens) for ~ EUR 399 or a similar Dollar amount on eBay Germany and USA. Here you have some movement capability. Add the wide angle bellows and with luck you get a 65 mm or 80 mm WA lens, paying a 3-digit amount for the works.
These lenses are still the old Boris designs, right?
