    ARGH@#!!. Before I throw something at the wall is there a trick? Or is something wrong with this prism? I can attaching the waist level with my eyes closed. Or the non-metering prism. But this thing is pushing me to the edge.

    Ok, Nick...mine's right here in front of me.
    Seems to go on just like the WLF. Set it on the mounting platform at a bit of a tilted back angle to catch the back slider things (on bottom of prism) with the back inside lip of screen area. Tilt it forward (to flush) and slide forward.

    I managed to get it fitted but it took more pushing then I think is normal. From looking at the camera body I think the right groove that the prism is supposed to slide into maybe smaller [bent?] then it should be. I don't know why the waist level fits so cleanly. Maybe it's a little thinner.

    It's working now. OTOH I'm not going to take it off either.

    Thanks

    Not even for the Rotary? I've the WLF, AEIII prism, and
    the Rotary. Bronica's Rotary is really splendid; very
    noticeable distortion but very bright and very
    sharp and I very satisfied. No more pain
    in the neck.

    I picked up the near new Rotary from eBay for around
    $170 and switched to off camera metering. Dan

    If I find a real cheap rotary I'll consider it but it'll go on the other body. Personally I like using the waist level but a metering prism comes in handy some times.

    I like the waist level also but on the ETs it's only
    practical for landscape mode. Of course a WLF can do
    for all shooting with the always upright 6x6. Dan

    Dan do you have the manual for the III prism? Or at least what does the switch underneath do? It's labeled 0,1,2 I think.

    That's built in EI compensation; 0 is none, 1 is .3, and
    2 is .6, or 1 or 2 1/3 stops. Use or not as you choose.

    At 0 the ISO set is the EI used by the meter to arrive
    at an exposure recommendation. At 1 or 2 that EI is
    reduced by 1 or 2 1/3 stops.

    I found my AEIII meter to give high readings even
    after making a reduction from the ISO when setting
    the film speed so I added .6 or 2/3 more
    with that switch.

    I'm quite sure that info is correct. I started using
    the rotary a couple of years ago. I'm basically a WLF
    type and that eye level was a pain in the neck,
    literally. I encounter a lot of verticals when
    working in the woods. Dan

    So it's more of a permenant correction? Then use the other dial on prism to adjust for each shot? Sounds like I better take the time to see how it's reading. Thanks.

    "So it's more of a permenant correction?"

    You could think of it that way. A 2/3 stop correction
    may bring it more in line with your previous metering.

    "Then use the other dial on prism to adjust for each shot?"

    That would be the +/- 2 stops compensation; as needed.
    In AE mode I usually used AE Lock.

    That finder has exposure lock. Did you know that?
    A manual is something to have. eBay's a place to look.
    The ETRSi and what goes with it are some sophisticated
    gear; many details and fine points. Dan

    I've got the camera manual which covers the prism a little. But that switch on the bottom wasn't mentioned any place. The camera manual is still on the Tamron website. Kind of hidden but it's there.
