This image has been inserted into Camerapedia because its copyright owner has explicitly allowed it. The copyright holder may be a Camerapedia editor or a third party who gave explicit permission for use within Wikipedia when asked by a Camerapedia editor.
The status of images within Camerapedia pages is very different from that of text. When granting Camerapedia permission to show the image, the copyright holder has not released the image under GFDL (or a Creative Commons or other copyleft license), put the image in the public domain, or agreed to its redistribution.
Before redistributing this image in any way (CD, other website, etc.), you must obtain the permission of the copyright owner. You can ask how to contact the copyright owner in the talk page of the corresponding Camerapedia article (when your browser shows the article, look for and click the "discussion" link).
If you want to reproduce a whole Camerapedia document under the terms of the GFDL and to insert the image in the same context in which it is found in Camerapedia, please ask the copyright owner for permission. Unless or until you receive this permission, you can only reproduce the text of the Camerapedia document without the images.
Inability to contact the copyright holder or lack of response from the copyright owner of course means that permission is not granted.
(If you are familiar with the rules that apply in English-language Wikipedia, please note that the rules here are very different.)
