Angenieux retrofocus - definition of Angenieux retrofocus in Encyclopedia (123 words) |
 | The Retrofocus photographic lens was invented in France in 1950 by Angenieux, and is characterized by a large negative meniscus lens element up front followed by four or five small elements in the rear. |
| The retrofocus lens has its focal point significantly further from the surface of the rearmost lens than would be the case in a lens of conventional construction. |
| Users of 35mm Single lens reflex SLR cameras appreciate the retrofocus construction, otherwise very short focus lenses would interfere with the operation of the mirror. |
| An introduction to Angenieux lenses (1136 words) |
| Pierre Angenieux, was born in July 1907 at St. Heand in the Loire Region, did not establish his optical company until 1935, and so may be considered a relative, if subsequently very successful, newcomer to lens manufacture. |
| Angenieux lenses may thus be found fitted to a range of the more popular middle-price Kodak cameras of that period that included the 620 rollfilm models as well as 35’s such as Retinettes and Pony 35’s. |
| Angenieux lenses faded from the general photographic market in the 1970’s as the company responded to Japanese competition by concentrating on the more specialised (and less cost-sensitive) military, medical and space-program markets, where it won considerable distinction. |
