    Hmm, middle ground. I'm thinking of a few MF normal or wide lenses that are
    f1.7 to f2.8 and some telephotos that are f3.5-f4.5. Basically faster or
    wider than my AF zooms.

    If specced up you can easily double the $105 dollar price of one of those
    screens - I was wondering about rule of thirds grid, not necessarily as I
    need it for that (I can guess quite well) rather it gives me more to align
    the horizon with. OTOH the advantage or not having optibrite on faster
    lenses is worth noticing.

    Perhaps I should get a basic one and see how it goes. I note from last
    weekend when using longer focal length lenses that most stuff was in focus,
    but then I was working at infinity fairly stopped down most of the time.

    I have one "slow" lens, a 300/4.5. It's usable with the non-bright screen,
    but you definitely notice it, and it's not an effect I would want with my
    everyday lenses. If I were using f/4.5 lenses a lot I would probably be
    at least annoyed with the darker screen. So, yeah, I would call f/4.5 a
    middle ground. f/5.6 would be a show-stopper.

    Once you install the screen, in practice, you aren't going to be swapping
    it out. I mean, you could, but let's be realistic, you won't. :) So you
    should expect to live with it for all of your lenses.

    Also note that, at least on my camera, the screen affects the spot meter
    when used with slow lenses. This doesn't matter for my usage, and there
    is no other effect on metering, but the spot meter may be a stop or more
    off with an f/4.5 lens. This will apply whether you get the bright
    version or not.
