Chris1878 0 Posted January 26, 2011 Hi all, While I'm not a CCTV guy we use then in our interactive installations. The model of camera we used changed so we had to start using a new camera. The problem is the new camera wont focus properly when we put our band-pass filter in it. The lens from the old model however when in the new camera focuses just fine. Bottom line we need to find similar lens to old version. Please find an image here. http://picasaweb.google.com/lh/photo/-neLbZVx15r5-ZsQc0rS1w?feat=directlink The lens is a 4mm-9mm. Where can I source these in the UK. TIA Chris. Share this post Link to post Share on other sites
