In the past they say to you "get rid of that lens cap", but today I say "lens cap protect your baby Diana lens". To keep this important piece of your camera you can try this tip!
In the past we’re told that we have forget the lens cap, but times are changing and your loved one – the Diana F+ have a little gleamy and new plastic eye and you want to keep it shiny forever. So, give this a try and protect your beloved camera.
Nice and easy! Just get some nylon black cord (or any other stuff, like little chains, for example), drill a little hole in your lens cap, tie up to the camera and pass it through the little hole you just made and make a strong knot within it. With this, you´ll never lose your lens cap ever! Your Diana+ will keep it´s bright plastic eye like new for a long long time.
This could also be done with any camera and its lens cap.
