[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I have a BM 135/4.5 Hektor serial number 1621324 with E39 filter thread and am trying to hook it up to my Visoflex 3 / Bellows 2 combo. I have the 16596G bellows adapter and can bayonet the complete lens on that way but would prefer to mount it so that I can get lower magnifications as well. I read the Bellows 2 instruction book and the Leica Catalogue no. 41 and ordered bellows ring 16558 and adapter tube 16472K which is what is suggested will work. The 16472K tube even has 1:4.5/135 engraved on it but unfortunately it does not work as the tube thread is significantly too large. The optical unit unscrews underneath the knurled focusing ring and in order to withdraw the optical unit you must also unscrew the leading "tapered" ring of the focusing ring. The optical unit has a thread that is slightly smaller in diameter than LTM thread and slightly larger than the thread of the 16558. Am I unscrewing in the correct place? .....Help! John Collier
