Hello,
Several of the SVS-C55 & SVS-C55IR type cameras come back with complaints about bad image or focus with the lens. The problem in these cases is actually that the larger part of the lens mount needs to be separated from the very thin metal part in order for the lens to function and focus properly. It might be a good idea to add to the description of the product that this thicker piece of the lens mount should be removed from the camera, leaving only the super thin lens mount where the lens should be screwed directly into. Who can make that happen?
