    That Technika III Ground glass thing again help.

    The early part of this post is here if anyone cares.
    http://www.largeformatphotography.in...to-replace-one

    I received a 4x5 Linhof Technika III "replacement" ground glass from Stephen Shuart. It is close enough to the correct size to fit inside the metal ground glass frame so thats good, but...
    The two flat springs that push the glass up against the flat machined surface don't reach far enough to actually push against the glass. The amount of space left in there makes me wonder if this camera originally had a fresnel screen on it.

    Did the 4x5 Technika III come with a fresnel and do I understand correctly that it was on the inside (lens side) of the ground glass?

    If I buy a generic fresnel and ground glass, who should I contact to put it all together and make sure its all set correctly for sharp pictures?

    thanks,
    Robert N

    I seem to remember that the III did indeed have its fresnel between the GG and lens.

    I don't know if I sent them my parts if they would work on it or not, being the age that it is and them new to Linhof.

    I used S.K.Grimes (www.skgrimes.com) to install and check out a BosScreen on a Technika V some years ago. You probably know of Grimes, they're well known in the LF community for the high quality of their work but they're not cheap. I don't remember what I paid and it would be dated anyhow.

    I would buy a fresnel from ebay seller "ssoliton11" and install the fresnel behind the groundglass. If needed, you can make extra padding around the edges of the fresnel with small bits of cardboard.

    Alternatively, if you prefer to work without a fresnel, just cut two strips of cardboard to the necessary thickness and insert them in between the groundglass and the metal springs. You just need a filler material. It doesn't need to be anything fancy or expensive.

    They are not new to Linhof. They have been repairing them for years. They are new only as far as being the official USA Linhof service center.

    Maybe someone out there who has a 4x5 Technika III can look at their ground glass and notice if it has a fresnel and see if its on the lens side or viewer side of the ground glass. BTW, this is the Tech III version 5
    Thanks!!

    Mine did not come with a fresnel, but I bought it used, so who knows if there used to be one there. I have added one in back, but the regular gg always seems to have rested on the springy things.

    My Tech III (version 4 I recall) did not come with a fresnell either, and I am quite certain it is still the original ground glass.

    Best,
