Where can I find a Tamron Fotovix repair manual
Repair manuals can be bought by certified repair centres. Sometimes you get the manuals when you have done the repair course at the firm. Not sure Tamron does so. But they most of the time don't sell these manuals to normal people, to avoid they start opening a lens, because they never will be able to put it together as a working lens, without the tools, like a collimator.
