    Ray Optics Simulation of Swarovski NL, SLW

    So can you tell from this simulation how well that would really work out in practice? Surely there's a reason why it isn't done.

    Ray Optics Simulation of Swarovski NL, SLW

    Noctivid doesn't have a fully flat field, or the strong pincushioning typical of other Leicas... I think your first image (in #3) illustrates the challenge of that combination, and why flatter designs resort to lower distortion. But what happens if you just make the initial converging lens of...
