I had a little accident with my camera the other day: please don't let your camera on the roof of your car and then drive your car. Now my lens is broken.
It's an old Yashica lens, it comes from the times where things were made to last, so it didn't completely shatter: the focus ring doesn't turn anymore but all the glass elements are intact.
I'm not interested to repair it because I already replaced it (it was really not an expensive lens) but is there anything useful I can make out of it?
Thank you.
