|1 Choose a suitable tube. An empty toilet roll can often work, but in this case it was too narrow for the Olympus lens. You can check first by seeing if your filter fits into the open end. My 52mm filter was a perfect fit. Now you need to cut off the closed end to make a tube. || |
2 Use a sharp knife or saw to cut through the plastic. But take special care. I don't want complaints from fingerless people!!!! I pressed the knife in to perforate around the plastic. A saw would have made a smoother cut but I was in a rush. Always am!
In this cap the whole inner protective plastic comes away with the unwanted top leaving a solid tube.
