    Computar Symmetrigon 150 180 210 /6.3

    First I want to thank you all who have helped me erlier on this site.
    Now I have questions about the Symmetrigons (the 4/4 designs actually, not the older 6/4).
    This is an interesting design, not like the standard plasmat type. Do they really cover 72 degrees or ir that just the cut-off-limit?
    Are all in #1-shutters? Filter sizes?
    I know from before that some mentioned the cross-sections of them. Are there somelitterature that is available about them? Id be very interested. Are they optimized for 1:5, 1:10 or 1:20? Are they APO-corrected?

    This is a lot of questions, but thank you in advance.

    "Are they APO-corrected?"

    the ones that were are engraved 'APO Computar Symmetrigon'

    "Are all in #1-shutters?"

    yes, all 3 of mine have been in #1 shutters

    "Filter sizes?"

    all 3 are different sized, the 150 measures 55mm, 210 takes 72mm

    "Are they optimized for 1:5, 1:10 or 1:20?"

    I believe they were optimized for inf. Very nice lenses, under valued, make sure it has it's "perfect lens shade" if you buy one.

    Have fun with the hunt.
