    Re: Prototype RF-coupled 4x5 camera

    I noticed that Ilford still makes 5" roll film during the ULF special order. except for the fact that you would lose individual sheet processing , would it be useful to have a 5x4/5x7 roll film back like the Horseman 6x9 backs do for 120 film? Probably not but let your mind wander a bit at the possibility. I'm sure arial cameras likely had something but you wouldn't want to hike with it.
    The magic you are looking for is in the work you are avoiding.

    Look up Linhof Aero Technika 5” roll backs. These things take 50’ of 5” (120mm) NATO spooled roll film or 60’ if it is ester base film. They would mount to any Technika 4 or later body but will not mount to a Graphlok back. I believe there was one that could mount to a Graflok but took less film and may not have given the 5x5” negative.

    Dude, I may be mistaken but until proven otherwise I think you've been trolled. The version 2 images look like renderings, not photographs of an actual object. The lens cross-section shown in http://www.aubreykingston.com/lfc-home#/lens-bellows/ isn't a Biogon formula, it is an early Russar. The version 1 images give the strong impression that it doesn't have a working RF.
