Hi, i want do do mote work with 9x12 folders, bur for price and convenience reasons with my Rollex patent Roll Film back. This fits on normal LF cameras from the Zeiss Ikon group (slide-in system) as my Ernemann Heag IV. The Ikon ideal would be great because of its Scheimpflug possibilities, but i read it has another back fitting system. Does anyone know if the Rollex Patent fits the Ideal? The alternative would be the Maximar, but I think it has no Scheimpflug... thanks!
