woodenbox while lining up lens and adjusting focal length. lens mount is ldpe with a 38mm hole. the lens is m39 thread and the plastic has a bit of give so its a really snug fit. |
rear view of wooden box. had to hack to the screen hole cos the workshop was shut and it was too hard to guess the focus as the numbers on the lens are no longer quite valid. |
on the left is the one which takes the cheap praktica camera. the other takes my phone. |
