    No, the Olympus patent suggests a single, fixed sensor whereas the
    Ricoh camera is basically a back panel assembly - with LCD, back/top
    plate controls, a handgrip and a battery - to which you can attach
    various combined lens/shutter/sensor assemblies. The Ricoh sensors
    are actually different sizes!

    The Ricoh isn't selling well. Of course it might be that Ricoh didn't
    expect to sell very many, in which case they won't be disappointed.

    Yup! A simple meniscus lens has substantially better optical quality
    than a multi-element lens. <\end sarcastic tag>

    : Proving you've never owned one. Because their lens is comprised of 2
    : elements in 2 groups with a leaf shutter between the elements. That's how
    : mine is configured, discovered when I cleaned and restored it to near-mint
    : condition.

    There were a variety of Brownies with (I strongly suspect) a variety fo lens
    configurations. You could both be right.
