    They're just plus diopters. A +1 diopter shifts your focus range so that the infinity focus mark on the knob is really focused at 1 meter and goes closer from that. A +2 diopter puts infinity at 1/2 meter, +3 places it at 1/3 meter, etc.

    Don't want to bring an old thread from the grave, but your post was very helpful Christopher!

    I just purchased a Rolleinar 2, and I'm looking forward to using it!

    A third - back from the grave Q. Does each of the diopter lenses need their own unique prism for the viewing lens?
    Thanks for any help in advance

    Another item- there is a #4 Rolleinar, but it is a very rare bird.

    Here is an image with a Rolleinar #2 on my Rolleiflex 2.8E -



    Plenty sharp. Remember this was shot wide open, or at f4 at the most. Depth of field becomes paper-thin when focusing that close.

    TBH, I would never use a standard TLR as a portrait camera other than for a head and shoulders shot. The use of Rolleinars will only add distorted perspective.
    I'm into painting with light - NOT painting by numbers!

    Sorry The FlyingCamera,
    This image is not sharp to me. I don't understand where your point of focus was. I acknowledge the DOF problems but the outer edges of the frame seem to be sharper than the centre.

    The problem is that the DoF is so shallow that it was hard to focus. Perhaps this isn't the best example, but I was working within the limitations of what was available to me- handheld, no flash, low lighting.

    Perhaps you'll like this one better -
