I'll advise you to find service manuals for your various cameras, either copies or online versions. You'll find that, to properly lubricate most sections of the mechanism, it must be disassembled, cleaned, and then lubricated as you reassemble it. The manuals will specify the types of lubricant, (there are at least two, oil and light grease, possibly three or more) where and how to apply. Clock oil is easily available, oil specified for large (pocket) watches would also be suitable.
