    Geronar 210mm thickness

    I am looking into popping one of these babies into a Polaroid 900 but don't have one in hand. It has to be 30mm or less from front to rear element front to back. Can one kind soul measure theirs for me? If the Geronar is too thick can someone suggest a "thinner" compact lens in 210 to 250mm?
    Thanks and God bless

    My 210/6.8 Caltar II-E (Calumet branded Geronar) measures about 1 13/16 or 46mm. I also checked my Nikkor-M 200/8, it measures 1 11/16 or just under 43mm. Sorry about that.

    I'm assuming you want the measurement from the front of the front element to the rear of the rear element with the shutter in between them. In other words, the total thickness of the lens.

    [Edit] I just measured a 150/9 G-Claron at about 35mm. Good luck finding any lens in a shutter that's 30mm or less.
