    Those are great.
    I have a Spiratone 135f1.8 in Minolta MC/MD mount on the way.
    Somewhere I read that the following were all the same:
    Sigma Sigmatel, Spiratone, Raynox, Polaris, Rokinor, Porst 135mm f1.8
    ?
    I forget.

    PORST was a trademark for the German camera shop "Hans Pors(ch)t".
    They were known for relabelling cameras and lenses, but also had several lenses, which were made exclusively for them.

    Most of their lenses are M42, or PK-mount and were made by Cosina, Tomyoka, or alike.

    Some of them are very good (i.e. 55mm f1.2), but others were rather unimpressive.
    You can find a lot of information on the internet.

    Best place to find them is German ebay, as they were mostly sold over here.

    I've got the Cosina 55 1.2 in Pentax K mount (adapted for Canon EOS and then NEX) and it is incredible.

    You read incorrect information then...There are several different optical designs out there for the various 135mm f1.8 lenses:
