Kodak Ektars



	The following still camera Ektars were documented in the Kodak Professional Handbook, 1952. This volume duplicated pages in Kodak Data Book: Lenses Shutters and Portra Lenses, Fourth Edition, 1952, for optics for small professional cameras, plus the Professional Handbook had exclusive pages for Commercial and Wide Field Ektars. This was apparently the only edition of the Kodak Professional Handbook to have been published, since a Kodak "Handbook News #2" in 1959 still lists the 1952 first edition as the current edition. This logo is a link to a lens test by Chris Perez.

ø These lenses were not listed in the data section of the Kodak Professional Handbook, but rather in a table--"CURRENT AND RECNT KODAK LENSES for PRESS, VIEW, and SIMILAR CAMERAS" specifing adapter ring sizes and mounting flange part numbers. Further, in another table in the section, "ATTACHING LENSES TO VIEW CAMERAS," only the 7 1/2 inch Ektar is mentioned and then grouped with other lenses using the Supermatic No 2, whereas in the former table, the shutter mounted version shares a flange with the f/4.5 12 inch Ektar.
+ In the table showing adapter ring sizes, this lens is shown as requiring a Ser VIII 54mm adapter, yet the table entries for the    8 1/2 inch Ektar and the 8 1/2 Commercial Ektar list Ser VII 44.5mm adapters. The 7 1/2 inch Ektar also uses the same    flange as the 12 inch Commercial Ektar, suggesting that the 7 1/2 inch lens was a big piece of glass. This is inconsistant with    the idea noted in the previous footnote that this lens could have been mounted in a Supermatic #2. Perhaps there were two    different 7 1/2 inch Ektars?
‡ These lenses were later offered in Synchro Compur shutters. Kodak data books no longer included lens
   and shutter data for professional cameras after 1952, so do not reflect these later Ektars for press and
   view cameras.

µ Kodak uses the qualitative phrase "circle of good definition with subject at infinity" but defines no quantitative measure

¶
Since this is such an excellent lens, it is natural to want to remount the stray example for use with another camera. Unfortunately, the linkages for shutter cocking and release don't lend themselves easily to this. To have this done by a qualified photo machinist would be likely to exceed the cost of a more modern lens of this length. See extended discussion on Medalist page.

‡ †	This booklet predates the first edition of the Kodak Reference Handbook and contains detailed information about many more lens models and considerable background information about Kodak lens design and production. Kodak issued replacement pages to registered owners of the original Kodak Reference Handbook which was published in a loose-leaf binder; the replacement pages contained updated information about new products and processes. Newer versions of the Handbook would have contained these pages. © dates in this material appear for 1940, 1942, 1943 and 1945 and perhaps other dates. One of the first separately bound Data Books was published in 1946 "For Revising Reference Handbooks," and noted as Second Printing.
