>>3341652Thanks. No, no guides from me, per se (see next image), but there's tons of DIY guides online to make them. The ones that helped me the most are,

Here's pics of the lens used for the photos shown with it. This is the front element group out of an older vintage lens I bought on eBay for $13. The lens had fungus all over it and deep inside all the other elements. I took it apart and cleaned everything perfectly, but the aluminum threads for the focusing mechanism were to weak that they literally crumbled to dust (like it was aluminum from a casting) so the lens was ruined regardless. I harvested what I could out of it and started making what you see here.
If you need specific lenses you may be able to find them on surplus shed (
https://www.surplusshed.com/ ). They arrive as bare glass so you need to build everything around them. The biggest tips I can give you are,
•Bellows are the best focusing mechanisms for DIY lenses sliding tubes are second.
•Plastic Body Caps and Rear Lens Caps make great mounts for lightweight DIY lenses.
•Reverse Rings for Macro are great for making moutns for heavyweight DIY lenses.
•JB Weld is the best epoxy for this stuff. Use Hot Glue for testing first.
•Paper Apertures can be amazing. The can go in front or behind the lenses if needed.
