[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]After reading all the mail about not using UV filters for protection, and finding my B&W was a single coated one, I went to remove it from my Noctilux. I held the lens by the base gripped the filter and turned, it unscrewed fairly easily, about normal. Then I realised I was unscrewing the lens assembly from the mount. I quickly tightened it up again and removed the filter gripping the lens unit not the base. After retightening the lens is properly aligned (aperture stop at the top etc). Should I be brave, unscrew it completely and put a dob of loctite on the threads, or leave it alone and be careful unscrewing filters, or ??? Thanks for any advice, Mike
