  1. con:
    EVF are hard to manually focus.
    They freeze at the moment of focus and take long enough to focus and
    set exposure that moving subjects have already changed position.
    poorer quality than OVF.
    uses power.

    No mirror, less expense, no hump, less weight, smaller cameras.
    Set to manual and adjust the shutter/aperture can you tell the
    resulting pictures on a dSLR or are you gessing with the
    -2..-1..v..+1..+2 scale? On an EVF not only you "see" the real picture
    as it's going to be stored, but there's no need to review the picture
    On a dSLR what you see in the optical viewfinder is not what you get
    until you reviewed with the rear LCD.
    On a DSLR, in burst mode, the mirror is up, and you are shooting blind;
    using the EVF, you see everything just like on a P&S optical and you
    can follow
    the subject.

    Finally, I bet that if photography had started with digital instead of
    film, the mirror TTL mechanism would never have been invented. It
    shakes the camera at exactly the time when you want it to be steady!

    EVF's are dim and hard to shake.

    Just lock up the mirror, and use a tripod.

    I've not seen that mode.
    Mirror lockup is for tripod work.
    There is a time delay between the action & the EVF & the final shot
    being taken.

    I'm sure Mr.Bolshoyhuy meant that the mirror is mostly up and the finder
    I've always wondered how following/panning shots (moving subject on
    motion blurred background) were done with an SLR, because the viewfinder
    is dark while the mirror is up and the shutter open.
    It's relatively easy with an RF camera, just keep the subject in the
    same relative spot in the viewfinder.
    There is also the little detail that on most EVF cameras, the EVF goes
    _blank_ while the image is being captured.
    Most of the delay with EVF cameras seems to be the autofocus locking-on,
    with contrast detection being slower than phase detection used in SLR

  5. If you can't hold a camera steady when that little mirror goes up,
    you've got some real problems.

    It's usually not noticeable, I guess at slow shutter speeds like half a
    second but even then you lock onto the motion & continue panning at that
    speed. I just tried at 1/4 second & it's not a problem, half second was
    a bit strange.

    I do like the instant feedback of an EVF for exposure though. That's
    just a whole different way of working, it can be fun.

    It shows you the older image on the VF/LCD so you don't notice it going
    away but there is a time lag.
