Are there any dslrs which will allow manual focusing with an external PC?

    The Olympus E500 is hard to focus manually,
    but it has a USB connection. Can I hook this
    up to a computer for pinsharp manual
    focusing?

    I think Olympus Studio can provide for computerized focus control, but
    I'm not 100% sure. You can ask here:

    I do have the Olympus Studio but all I have
    figured out so far is to able to set the AF &
    MF settings via the computer. It doesn't
    seem to do real-time focusing.

    With all the testing I've done it is still
    necessary to use focus bracketing for
    absolute focusing. And this takes time and
    memory.

    If the coming E3 has real-time computer
    focusing I'll buy it straight away, and also
    a small laptop which will effectively
    increase the viewfinder image area by several
    orders of magnitude. Also, the computer can
    brighten the enlarged viewfinder image in
    gloomy conditions.

    A camera with a high pixel sensor needs good
    focusing to make use of all those pixels;
    it's absolutely essential.

  4. There is Olympus Studio which allows computer controlled shooting, but I don't
    think it provides an on screen image before focusing for the E-500 since the
    sensor doesn't support continous reading. The newest Olympus cameras (E-330,
    E-410, E-510) and the Panasonic L1 have Live View, which in manual focusing
    mode can enlarge the image 7 or 10 times on the LCD screen (only 10 times for
    the older E-330/L1). I'm just about to pick up my E-510 that I pre-ordered
    some time ago, so US shipments are starting now.

    I don't think any computer monitor is going to permit pin sharp
    focusing, which is why I always opt for optical view finders.. much
    sharper than any digital representation, My Apple Cinema Display is
    sharp, but cant' hold a candle to the view finders in my Nikon SLR's or
    DSLR's. Same reason I don't rely on the little screen on the back of
    my DSLR to make critical judegments... just lets me know if I really
    screwed up
    the composition. No, you could not sell me a camera without and sharp
    optical finder.

    When I used remote control software on a Nikon D70, it activated the AF
    by default. Convievably, newer software would let you adjust the active
    AF point a little but I doubt much more is possible. EVF cameras allow
    zooming in to foccus so that in itself is not a problem.
