    TLR Paralax correction

    My Rolleicord Va has a mask in the viewfinder which moves down as I focus closer to compensate for the fact that the viewing lens is above the taking lens. My Yashicamat does not have a mask like this. Do any other TLRs have this feature?

    The Rolleiflex, of course, has this.

    It doesn't appear the Zeiss Ikon Ikoflex has this, however, the Proxar close-up lens sets for this camera are corrected for parallax.

    The Mamiya C330 has a parallax indicator in the viewfinder which indicates how the top of the image area moves down on the screen.

    I am reasonably confident that at least one design (though I forget which) tilted the whole reflex box for parallax compensation.

    There is also a very useful tripod adaptor for it that simply moves the taking lens into the exact position that the viewfinder lens occupied during composition and focusing. This allows very close focusing without parallax issues.

    I think it was called a Paramender. You can of course achieve exactly the same effect, a good deal cheaper, by raising your centre column by the same amount. As far as I recall, 4 fingers at the first knuckle worked fine for me.

    The paramender beats the "4-finger method", Roger, when the camera is tilted to any degree away from the axis of the centre column. It places the taking lens in the correct position no matter the spatial orientation of the camera.

    Absolutely true, and I stand corrected except when using a Benbo with the camera axis in line with the centre column. I was thinking of the only times I have used this technique, which is with extreme wide-angles where careful levelling is the norm.

    An excellent example of how one should carefully read anyone's posts, probing for inconsistencies and unstated assumptions. Me culpa, though not necessarily maxima.

    Cheers,

    From time to time I have seen Mamiya Paramenders with a marking at 45mm displacement. This is suitable for the Yashicas and similar TLRs with a 45mm lens axis separation. The Mamiya Cs are 50mm.
    I feel, therefore I photograph.

    The 1930's Voigtlander SUPERB has this feature... I think....
