Hello, I am about to take delivery of a used LX5 and 'genuine' wide angle converter. I understand that you have to 'programme' the camera via the menu when using the wide angle lens. I have both the basic operating instructions for the camera and for the converter, but neither deal with this. Please could someone give me an easy step by step guide to doing what is necessary. Assume that I am stupid in advising me what to do - or it might just be advancing years... Many thanks.
