    8x10 Prototype

    Hello,

    This is a follow up to my previous 5x7 build (found here).
    Again, it's a non-folding/wide-angle design to primarily fit the very beefy Super-Angulon 165 f8. It can also acomodate a 210mm lens focused to about 5 feet. I improved many things, mainly the lever driven spring back, added front-shift and front-tilt movements and (hopefully) refined the design. The bellow frames are held in place with neodymium magnets, as is the rotating back.
    All wooden parts are made from Bubinga, (almost) all metal is 6061 aluminum, the black rods/tubes are carbon fiber, the ground glass is hand-ground and laser scored 1/8" acrylic, the back leaf-springs are cut from phosphor bronze and the bellows are made out of the Thorlabs BK5 fabric.

    Thoughts and suggestions are very welcome.

    Stunning work! I'm also jealous your camera has its own Metro stop.

    Don't tell me that's the exact, official logo of the Paris Metro ...

    No, but it's not too far off...
    Some very smart features, I especially like the magnet approach. Brilliant.
    Beautiful workmanship, and a lot of thought went into this, it's quite obvious.
    For my own taste, I'm not a huge fan of some of the minor styling details, but they don't detract from the camera, either.
    For example, I would find the level on top of the rear standard quite distracting while working, yet it is in the perfect place should I need to glance quickly at it.
    Have you incorporated zero detents into any of the movements?
    Congratulations, it's a superb piece of work.

    I think you're going to want some kind of wide angle/bag bellows if you're primarily shooting with the 165 Super Angulon. It looks like you'll have some mechanical vignetting at full front rise based on the 6th picture.

    Nice camera! Can it be massively produced?

    Metro, Schmetro ...

    I like to think that I paid homage (sort of) to one of my favourite comics books:



    ... and it's the first letter of my last name.

    I have tried using bag bellows on a previous build, and they looked just too hideous.
    Full rise with the 165 f8 on this camera would be well past the edge of the image circle, but yes, the bellows could be in the way.
