    I just picked up a split prism focusing screen from Katz Eye Optics because I use several manual focus lenses and I have to wonder why manufacturers stopped equipping bodies with this type of focusing screen.

    It works as advertised and if you do any manual focusing you should consider it required equipment. I bought it with the ultrabright coating, and it stays bright to f/2.8 and it's still perfectly usable with f/4-f/5.6 lenses.

    This is view through the viewfinder now:

    Doesn't it usually make the metering inaccurate though?

    It would depend on the location on the exposure meter in your body.

    Sorry, I'm a noob but I've seen these focusing screens before but couldn't figure out how it helps with MF. What does this mean?

    instead of using your judgement you align the split prism


    center is in focus, notice how the bars line up and the microprisms are clear

    FUCKING WERD


    I can't manual focus without a split due to my glasses and the diopters usually don't adjust enough to help.

    I'd like to manual focus more, but I can never tell if I'm right. This will definitely solve that problem.

    $105 is pretty pricey...don't know if I need to MF that much :o

    How does this work with AF? I can imagine it would be a little weird...

    I love the split prism on my OM-2 but find it kind of annoying when I'm photographing things with lots of horizontal lines.

    it wont.

    you either: turn it off and use your AF lens in manual mode.

    or mainly,

    now you are able to use older, manual only lens, on digitals that didn't have a SP.

    The D90 lets you know if you are in focus or not. I'm sure other dslrs have this feature too.

    Split prisms are :bigthumb:

    That's kinda what I figured, works the same way with AF only "automated".

    Then again this seems like it would get in the way of composition and just your general view of your frame when you haven't locked focus yet. The screen on my OM-2 is either sharp or wildly out of focus.

    :rofl::rofl::rofl::rofl: WTF are you talking about? AF works just fine, the new screen has no effect on any camera or lens functions at all. Focus and metering work exactly as they did before.

    No it doesn't. Below f/5.6 the viewfinder is a bit dark, but everything still works just fine.

    f/2.8:

    A lot of misconceptions up in this thread. :hsugh:

    sorry, my bad, i didn't properly write my responce, let me re try this



    If you are going to shoot with jus AF, it’s kind of pointless. The only time I could see it being used with AF is when you are zeroing in on desired focally point change on a subject. But it’s main reason is for shooting in manual. And for those that have non- auto focus lens, those are now a lot more useful with this. That is the main reason I would buy one.

    From their web site.
