Experimenting with a Fotodiox FD to Micro 4/3 adapter has been fantastic. I'm thrilled to be able to mount some great old glass to a Panasonic GF2 Lumix. So far I have tried a Canon 28 f2.8, 70-150mm f4-5.6 and a 200mm f4. All focal lengths display a 2x factor compared to a 35mm film camera. Below are some hand held stills from the Canon 200mm f4 that are analogous to a 400mm reach. ICPix will post more images as we experiment and we may try our hand at some video as well. Let us know your thoughts.
