Spec Notes
ABSENT FROM AGFA'S OWN INSTRUCTION BOOK, whose alternative-lens passage names only the 90 and the 35 and whose viewfinder carries frames for 35, 50 and 90 alone - that book edition predates this lens. It SHIPPED: a 1959 handbook enumerates it and specimens survive. An introduction of about 1959 is consistent with the evidence but is NOT STATED by any source, so no year is recorded. AGFA PUBLISHES NO OPTICAL SPECIFICATION FOR THIS LENS. Its instruction book is captioned illustrations, not a spec table: no groups, no filter thread, no minimum focus, no blade count, no weight, no per-lens production years exist in any source consulted. They are ABSENT rather than zero. FILTER SIZE OMITTED DELIBERATELY: Agfa says the 35, 50 and 90 share a 37 mm outside-diameter FRONT CELL so one filter set serves all three - an outside diameter is not a thread - and a collector reference gives 35 mm / 40.5 mm / 62 mm instead.
