    Lens Nimenclature and lens Designe: Raptar vs Paragon

    Simply put: Is there a difference in lens design between lenses labeled "Raptar" and "Paragon"?

    There are only three types of mounting flanges; too big, too small and wrong thread!

    They are two different companies. Both the name Raptar (Wollensak) & Paragon (Ilex) are trade names for various optical formula lenses.

    They are trade names more than lens types. A Raptar was a Wollensak Velostigmat which was coated. Both are Tessar type four element. They simply changed the name. A Paragon was usually a four element Tessar type as well, but apparently the Pagagon process lenses were Plasmat design.

    Here are the optical designs of many commonly encountered Raptar lenses, from the 1954 Wollensak catalog.
