Recently I added a new vintage lens to my collection: a 1/2” Wollensak in a c-mount. C-mount lenses are commonly associated with 16mm movie and closed-circuit security cameras and given the design of the micro 4/3 system, can now be adapted to fit on a Lumix body. On a G1 this particular lens is equivalent to a 25mm wide-angle. Obviously what’s interesting is that the lens itself generates a circular image on the G1’s sensor. The circular image is caused by the lens not filling the entire frame of the micro 4/3 chip. Some may feel such a lens is too limited or unworkable, but in my case it is an interesting creative experiment.
