    I have 2 Yashicamats in my reapir shop and want to know the differences and maybe a date of manufacture and which is more desireable.

    The older Yashicamat....
    It has a different logo on the hood, not the typical Y in a circle.
    The serial number on the top of the viewfinder is 65427.
    There are no markings on the winder side tank.
    The lens is a Lumaxar 75mm 3.5, taking lens s/n 42755, viewer s/n 62806
    The door clasp in the front is more like a hook shape flat metal.
    There are 4 steps up to the front oval YASHICA MAT logo
    Everything else seems typical of Yashicamats

    The newer looking Yashicamat...
    It has a tyical logo on the hood, the Y in a circle.
    The serial number on the top of the viewfinder is 5871381
    There are markings on the winder side tank, says
    Yashima Opt. IND. CO. LTD, made in Japan.
    The lens is a Lumaxar 80mm 3.5, taking lens s/n 30486, viewer s/n 63658
    The door clasp in the front is a square shaped metal.
    There are 5 steps up to the front oval YASHICA MAT logo
    Everything else seems typical of Yashicamats.

    I haven't been able to find these differences listed anywhere on the internet and would like to know a bit more about the differences?

    Thanks,
    Paul Ron, NYC

    Paul, there are some variations with same name cameras, I wish I knew more about what you describe. I can only direct you to the one and only Mark Hama, whom used to work for Yashica and guaranteed knows a lot about them. His website is:

    http://www.markhama.com/

    Send him a query. Good luck and if you find out, let me know, I would like to know also.

    Hello Dmitri,

    The Lumaxar lenses were only used by Yashica for about one year. Very few were 75mm and I would think that 95% of all Lumaxar lenses used were 80mm. I also have a Mat with Lumaxar 80mm lenses. Both the lenses and the shutter used with them are odd and unlike all other Yashica TLRs. Differences are: (1) Above the Y on the name plate you will see the ? registration symbol. (2) The shutter speed settings are: B, 1, 2, 5, 10, 25, 50, 100, 250 and 500. All other Yashicas are: B, 1, 2, 4, 8, 15, 30, 60, 125, 250 and 500. (3) All other Yashica TLR lenses were make by the Tomioka Optical Company but the Lumaxar were made in West Germany. Some people say the Lumaxar lenses were made by Tomioka but Mark Hama says they came from Germany and were installed in the Nagano, Japan factory. I also read an article, written by a professor of photography at SMU in Texas, in which he stated that the color coating used on the Lumaxar was only available in German at the time they were used. When the Lumaxar was used the best Yashica lens was the 3 element/3 group Yashikor and the 4 element/3 group Yashinon was not being produced. The Lumaxar was however a 4 element/3 group lens very similar to the Zeiss Tessar. All Lumaxar lenses are rare but the 75mm is more rare than the 80mm. Your can remove the viewing screen by removing 4 tiny screws. Once removed you can clean the mirror and the back of the viewing lens but you will not be able to clean the rear of the taking lens. That job should be left to a professional camera repairman. The serial on mine is 70434 and I would think that your's is lower ... let me know.

    Tom

    I looked at mine and it seems to be like your newer version, 5 step viewfinder, SN 75350 and it has the <EP> to the left of it. It's a 80/3.5 Lumaxar SN 118161 and the viewing lens is also a Lumaxar SN 119319. It has the yellow Y in front of a silver triangle, all enclosed in a black with silver rims medallion that sits on top of the folding viewfinder.

    I believe the gentleman that inquired about it, his name is Dmitri, also asked me a few questions about a Yashica with Lumaxar a few months ago and I directed him to the PhotoNet. We kept in touch briefly, since we do share a very similar first name. ;)

    I do think that Mark Hama might have the right answers...

    Another interesting responce is this one on PhotoNet which is very interesting about the name change...

    Hi, Paul Your newer-looking Y'Mat is actually a very early model, mate. The first Y'Mats from around 1957 had "Lumaxar" lenses, which was changed to "Yashinon" after a couple of years reputedly because of legal threats from a British lens maker (Wray?) who had used a similar name for years. Apparently though, despite the change of name, they are optically identical being the same excellent Tessar-style 4 element design.


    It's all coming together, how much is actual fact is another mission. Thanks, lets see what else we find.

    Oh, that is interesting, I didn't know that about Wray. Worth looking into it. :)

    Thanks for sharing.

    All this info comes from a Russian site, I had it translated with Google and then I tried to make some sense.
