Glass marble lens in Micro Four Thirds mount

Today I thought that it would be interesting to use a glass marble as photographic lens! So I made this MFT bayonet mount with a marble inside. The marble in use has a diameter of 25.4mm and is probably rather made out of plastic and not out of real glass.

Building the lens is easy: Just glue thelower two pieces together, then insert the tube with the marble. "Focusing" can be achieved by moving this tube back and forth.

The lower two pieces make also a perfectly fitting Micro Four Thirds bayonet mount in case you need one for other experiments.

The contrast of the sample photos is
enhanced in photoshop afterwards. Otherwise this is how they come out of the camera.
