Loose Fujica 35 ee lens barrel? Here's the solution which I found by going the wrong way about it ( I disassembled the camera unnecessarily). Open the back and you will spot the two grooves on either side of the lens back element. Use a couple of precision screwdrivers or anything appropriate and safe and turn it around if I remember, clockwise. I am posting this because I haven't used my Fujica for 2 years, as there's nothing online to describe such a simple fix. A repairer suggested that the lens barrel had to be opened but it doesn't at all. Hope this helps someone out there.
Until next time,
