I'm looking to learn how to fully clean/repair lenses more than simply puffing with a blower and wiping with a cloth...
I have a bunch of old P entax SMC lenses that I don't mind pulling apart (two of them have a little fungus) and want to use them to practice repairing old manual primes. Unfortunately I can't find much online, nor any books on the topic. I have even tried to find information on specific lenses (Pentax, Nikkor etc.) but still nothing detailed. So essentially I am asking if anyone knows of books/websites etc. here I might be able to learn anything related to pulling lenses apart, cleaning/repairing them, and putting them back together again (all stages being vital!).
I understand that this is as much a science as a skill, with precision and math being vital... but surely the talented folks repairing lenses haven't all learnt through apprenticeship?
I've been pulling apart and re-assembling things since I was a kid (to various degrees of success), and sooner or later I'm just going to dive in... so please educate me before I make a mess!
