More people realizing EVF's are better than optical viewfinders

    Which camera?

    Of course one can be better. You can not focus as accurately with an optical viewfinder as with a modern EVF, it's not possible.

    the delay of the human eye can't be avoided.

    adding another delay for the evf is the issue.[/QUOTE]

    Surely there is no reason that thedelay associated with an EVF has to
    be so long that it interferes with the photography? Even today image
    data can be moved at very high speed. It's just that as yet nobody has
    got around to doing it in an EVF camera. Some day, they will.

    there's this new thing called autofocus, where the camera focuses for
    you.

    I'm not so sure. There are cameras combining sensors and processors on
    one chip which can produce images several times faster than commercial
    frame rates. While the interval between frames is real, it is so short
    that it cannot be detected by the human eye. The biggest problem
    remaining may be matching this with a suitable electronic display.

    And it provides reasonably accurate results, unless the photographer
    decides to create a sharp point, at a place other than where the camera
    decides. I frequently use manual focus for macro and landscape work.

    What? Not even with a decent split-image screen?

    Assuming it knows where you want it to focus.

    Sony HX200V - required for light weight and extreme zoom (810 mm
    equivalent).

    Nah! The technology knows better than you.

    No, but it can be reduced or rather it's effect can be reduced.
    That's why you can blink faster than you can 'see'
    And why time appears to slow down during an accident.
    The images take a shorter route to the brain by not going through a type of recognition process.
    Also the corners of our eyes are faster reacting whicyh is why some can see lights flickering out of teh corner of their eye.

    yes there's no doubt about the delay but that doesn't automatically make EVFs better or worse as it depends on the use it's put to.

    I found that it's easier just to focus the damned thing than to diddle
    around trying to get the active autofocus spot onto the thing I needed
    to have in focus. And that a split-image screen made manual focusing a
    lot easier but threw the autofocus off a bit.

    doesn't matter.
    it can.

    it may not matter in many use cases and most people may not care
    anyway, but it's *always* going to be there. there is *no* way around
    that.
    that's another issue, and no display can replace the original scene.

    it provides more accurate results in most cases, particularly if the
    subject is moving.

    it's not possible for a human to focus on a moving subject while
    maintaining accurate focus as it moves.

    there will always be edge cases where a human can do better but those
    are few and getting fewer.

    it usually does and it keeps getting better at it, such as with face
    recognition.

    there are cameras with optical viewfinders that weigh *less* than ones
    with evf, but if someone is choosing based on weight then quality is
    not a priority and lag isn't a concern. it's still going to have a lag,
    they just don't care.

    Are you saying that there is no limit to the ability of the eye to
    detect visual interuption? Surely not.

    who said anything about moving subjects.
    Use of manual focus for macro and landscape is not exactly an edge case.

    moving subjects is the most common case.
    macro is definitely an edge case. in fact, it requires a special
    purpose lens, called a macro lens. there are also extension tubes,
    bellows, etc. that can be used.

    landscape is nearly always focus at infinity and generally using a wide
    angle where depth of field takes care of any focusing errors. there are
    exceptions (there always are) but those are edge cases.

    the reality is that autofocus will focus better and faster than humans
    do in the vast majority of cases. not all, but nobody said it was
    perfect. just another one of your usual straw men.

    Oh! thanks for that information. Please define precisely what you mean
    by edge case.


    Nearly always??
    Please define the set from which you draw your conclusion, then
    eliminate the "I've been there," memorial snapshot.

    Usually faster, assuming one has a fast focusing lens.
    Your response tells us that you do not do serious landscape, or macro work.
    I suppose you also call setting a hyperfocal distance an edge case.
