The focusplane of a fisheye is flat. This means that subjects in the periferal areas may have a focus distance of 10 cm even if they in real life are 10 meters away. So if you shoot on full aperture and focus at 10 cm you get sharp corners and no focus in centre. Of course it is also the same the other way around. http://www.panoramas.dk/panorama/fisheye-focus/fisheye-focus.jpg Hans ------------------------------------ -- <*> Wiki: http://wiki.panotools.org <*> User Guidelines: http://wiki.panotools.org/User_Guidelines <*> Nabble (Web) http://www.nabble.com/PanoToolsNG-f15658.html <*> NG Member Map http://www.panomaps.com/ng <*> Moderators/List Admins: #removed# Yahoo!
