    Hi guys,

    Meanwhile we 've worked on a retro setup. But what do you think about this angle in front? It's a lots less steeper.

    Thanks.

    Peter,

    I think this might work, nevertheless the calculation of your projection axis should be done with the center beam, not outer beam.
    The most important thing in your new Setup is the much smaller Screen and that you can use longer optics than before.

    Every Video Guy still would kill you for that, but I would say it will work, did a couple of these angles with Dl2s, 3s and similar

    Best

    Rolf,

    What exactly do you mean by longer optics? 1.2 or 0.8 lens?

    I've included a new steeper design. What do you think about that?

    Thanks,

    Peter

    Peter,

    with 0.8 Optics this Setup would never work, as 0.8 needs to be "mostly" on axis.

    With 1.2 and beyond the game looks easier as you got much more depth in your focus.

    Regarding Distance this looks to me like a classic Zoom Lens like 1.5 - 2.5 or similar. And that's what I have done before with DL2s in this angle, which worked.

    In a few months I am hopeful to be releasing a lens that will do asymmetrical parabolic distortion. Basically extreme reverse keystoning. The lens theoretically should allow for angles of close to 70 degrees off axis. I am speculating only a 15% light loss.
