I really like the chives. No matter how hard I tried, I couldn't get a single thing (as far as I could see) in focus with the f/2 aperture disc in, so realised I had to embrace the fact. It broke when I was focussing with the f/8 disc on some close leaves. So I was extending rather that compressing it. The ring that the optic swap assembly is mounted in came off the smaller one that is connected to the corrugated tube. I'm assuming I can repair it with glue but am wary that a repair will fail in the future. I need to remove the lens assembly but am unsure how to do it without the tool that comes with the alternative optic swap units, I see three little tabs that the tool must engage with. Pete, do you know how the tool engages with these? If I can do a successful repair, I think I might try to find a glass lens insert, as I can see a lot of potential in this strange little thing.
