I've been out today trying to get a tool for undoing and removing the lens off the lens panel of a LF camera. While they know what I'm talking about, none of the shops seem to know where to actually get the tool. I believe some of you refer to it as a "lens spanner" while others on the web call it a wrench. Anyone know of a suitable shop I should/could contact? I need it to remove the lens on my panel to clean the rear element (dust or pollen in there). Cheers!
