I’ve been messing around with an old projector lens from a Kodak slide projector. I printed a barrel that slips over the lens that has m42 threading on the end and attached an m42 to E-mount helicoid to make focusing easier. I can get a pretty clean focus at infinity and the field of focus is surprisingly wide
I printed a barrel to go over this one as well so it would fit in a m42 helicoid so I could focus, unfortunately though infinity on this lens is at 16mm and the only way I can currently get that is literally holding the lens in the open mount hole.
I have this experience with most paper towel dispensers when I follow the directions. Oddly… just grabbing the middle (where there are no vertical edges and less opportunities to rip) works everytime.
