Yesterday I bought an Olympus OM-1n with a thoroughly fungus destroyed lens (I used this as a bargaining chip for the body, it wasn't a surprise). I was wondering if it would be possible to take apart the lens, gut the insides, and then turn the remaining barrel into a pinhole lens. I know I can make a pinhole out of a body cap but I really don't want to do that, I'd rather try to salvage some sort of use out of this lens rather than chuck the whole thing. I've tried to look for a blog or video on how to gut a lens, but everything I've found so far has been how to clean/fix a lens so their main interest is having everything go back together and work properly. I want a lens-shaped shell when I'm done. Then I'll figure out how to install a fixed pinhole aperture. The camera and lens are currently at the camera store for some body repair (I didn't have the body cap so I left the lens on to protect the mirror). I'm willing to just grab some tools and dive in, the lens is already junk there's nothing I can do to make it worse than worthless. I've looked at my same lens that is in pristine condition (and will not be used for experiementation) and it looks like I'll start from the mount end? Any advice will be greatly appreciated.
