I recently picked up a Beaulieu 4008 ZM II with the ANGENIEUX 1.9/8-64mm lens.
When zooming out to a wide angle a squealing sound / squeaky like noise occurs. This noise only occurs during the second half of the zoom range (from approximately 30mm to 8mm). If I let the camera sit by the window in the sunshine for a bit (warm it up) this noise goes away and the zoom is quiet. I assume this must be a lubrication issue(?).
Does someone know how I might try to lubricate the Reglomatic Zoom Control on this camera? I’m tempted to hit it with some DeoxIT, but I’m not sure if that’s a good idea and I don’t want to make things worse.
Any advice would be appreciated. Thanks!
