richardtheboffin 0 Posted April 7, 2014 I am struggling getting a big 60x lens on a panasonic wv CL934 box camera back focused properly. The camera has an auto back focus which doesn't quite work. My limited understanding with box cameras and lenses is that I should set the zoom to wide and the focus to far and then let the camera do it's auto backfocus. Once set correctly, the image should stay in focus through the whole zoom range? Any pointers? Share this post Link to post Share on other sites

Cameras without auto back focus requires setup in low light or welding filter with iris almost fully open. Auto back focus should not be confused with Auto focus...
