    Probably the most interesting announcements of PMA, for me. CMOS sensors
    from Matsushita? If they can control the noise, they've got a couple of
    winners. Pricing is odd, though. The model with IS is only a $100 (US) more
    than the lower model? Who would bother with the lower model?

    Because it's smaller?

    Many expect Nikon to announce a FF or perhaps near-FF, at 1.1x.
    We'll see...

    I agree. You are exactly right.

    To achieve the same photon shot noise levels, a sensor 1/4 the area must use
    an exposure four times longer.

    Thus the larger camera seems to be four times more sensitive. ISO 800 here
    looks like what the 4/3 users see at ISO 200.

    But noise goes down as the square root of the measurement, so the amplitude
    of the 4/3 camera noise is only twice that of the FF camera.

    So, as you point out, the smaller camera is only twice as bad.

    So while a photographer would find the 4/3 camera to have "four times the
    noise", we theoreticians realize that it's only twice the noise.

    I agree - the new bodies are a throwback to an earlier age - I did
    admire Oly for going with bodies that were all 'digital', ie the lens
    mount being flush against the left edge.

    When you state "left edge", I can only assume that you mean when holding
    the camera for use.
    If you actualy look at the picture if the Oly P1 on dpreview.com you
    will see that the lensmount is closer to the left hand edge of the
    camera body than on the Evolt 1.
    It looks like Olympus decided that the more complicated porromirror
    finder and sideways swinging reflex mirror added too much bulk to the
    left hand side of the camera body.
    The hump for the pentaprism isn't any taller than the box that they hid
    the porromirror finder from the Evolt 1 in.

    I believe that they emphasis on "telecentricity" requirement for
    "digital" lenses has made the FourThirds un-nessesarily bulky compared
    to film SLR cameras that have a similar negative size to the 4/3 sensor.
    The Olympus Pen-F was the roughly same size as the Evolt 500, but the
    1/2 135 frame it makes is twice as tall as a 4/3 sensor.
    Pentax made a tiny film SLR camera (the Auto110) using 110 cartridge
    film, which has a frame size similar to a 4/3 sensor.
    I could probably fit 4 Auto110 cameras with 24mm lens attached into the
    same volume required for just the Evolt 1 body alone.

    Canon, Pentax, Nikon and Sigma have demonstrated with their own DSLR
    cameras and lenses that the whole "telecentricity" emphasis was merely a
    boondoggle and had no practical reason behind.
    Maybe it was done to justify a new camera design that required
    purchasing new lenses or an expensive adapter, rather than using
    existing Olympus OM SLR lenses straight out of the box.

    Do you mean lenses that are wide angle on a 4/3 camera (eg: 17mm and
    shorter), or do you mean lenses that would be wide angle on a full 135
    frame or APS-C but used on a 4/3 camera (eg: 35mm and shorter)?

    The fact that wide angle lenses have always had a light fall-off problem
    at wide apertures (some lose a full 2 stops from the centre to the edge)
    makes me uncaring of the problem (that has always been there) if it
    shows up on larger sensor cameras.

    I suppose which part of the world you live in.
    The adapter was never offered free as part of the camera kit in
    Australia, to the best of my knowledge.

    In addition to being smaller, there is an underwater case that was announced
    for the E-410. The grip is different between the two. Finally, the E-410 will
    be available about 2-3 months sooner than the E-510.
