I would recommend the "Leica Camera Repair Book" by Thomas Tomosy, not because it is a good book, it is only fair, but, because it has a section on how to disassemble a Hektor lens. The infinity focus is adjusted by a shim between vulcanite section and the focusing index dot. I would test the lens at infinity (at least 3.5 km or 2 mi) and, if it is off and not improved by moving the optical unit away from the film plane, I would remove the present shim and make up progressively smaller shim packs until things are right. If this seems like a great deal to much work, I agree. I had mine collimated and CLAed for $100US and I paid the chap with a song in my heart. Cheers John Collier PS: After infinity is all worked out you will still probably have to adjust the lenses focusing cam mechanism....not for the feint of heart. > From: Andrew Moore <dmm@bronze.lcs.mit.edu> > > I have a Hektor 135/4.5, in Leica screw mount, with a removable lens head. > I've had excellent (understatement) results with it on the viso/bellows. > I'm almost positive that the focusing tube and head aren't a matched set, > and focus is in fact off by about 3 feet at a distance of 25 feet or so. > > Does anyone know of a do-it-yourself method of bringing things back into > alignment?
