    90mm Optar similar to 90mm Angulon?

    Just wondering if these two tiny 90mm lenses are similar in optical design?

    No. Absolutely not. The Raptar/Optar is a 4 elements in 4 groups double Gauss type. The Angulon is a 6 elements in 2 groups angulon type, some refer to it as a reversed dagor type.

    Don't you think its time for you to learn how to use a search engine, e.g., Google?
