Spec Notes
f/3.8, NOT f/3.5 — confirmed by three Kodak documents. A widely-read collector site lists a "135/3.5" for the Ektra; that is the HASSELBLAD 1600F/1000F Kodak Ektar 135mm f/3.5, a different lens on a different mount, and it is sold as such by dealers. Do not merge them and do not lend one the other's numbers. MINIMUM APERTURE NOT SOURCED: Kodak's instruction book prints aperture scales for the three shorter lenses but not for the two telephotos. FILTER: Series VI inserted directly into the lens barrel and held with a double-threaded Kodak Retaining Ring — no adapter ring. Min focus 4 ft (122 cm), stated in the instruction book. 1941 list price $130.00.
