    You are welcome. - BTW, now you know one. I own my E400 personally. (Yes, it
    burnt a hole into my pocket, but I have no regrets. It's a fine scope. It's
    better than the cheaper E200 for photomicrography.) I assume many amateurs
    will follow in the next couple years.

    Another thing I learnt with my Ortholux: When using Achromats with a smaller
    CCD that mainly records the action inside a limited FOV (field of view),
    even without using a compensating eyepiece (such as the Leitz Periplan
    ocular), I cannot see any degradation due to an incomplete correction for
    lateral chromatic aberration. But with your excellent 40x APO lens at NA
    0.95, it is most likely very obvious to see a difference.

    Hence, there are at least three "cost groups" for amateur microscopy:

    1) Very low cost (new and old) -> should not worry about compensating
    oculars. Right?
    2) Medium to high cost (older equipment) -> Has Fluor and/or APO lenses ->
    must worry about compensating oculars
    3) High cost (new or rather new equipment) -> quite often does not need to
    worry about compensating oculars

    BTW, I am afraid that cost effective full 35mm format image sensors will
    remain an expensive commodity for quite some time. Nikon with their decision
    to stick with the DX format (see the new D2X) does not exactly send a
    message that they believe in the need for full format image sensors. But we
    shall know in a couple of years.
