Panasonic GH2 using a C Mount Fujinon 17.5-105 mm F 1.8 Lens

I recently purchased this fine piece of glass to use with my Panasonic GH2. Being a C Mount lens it required an adapter plate, the problem was the flange distance was not right on the money and the lens would not focus properly. I needed to make a small shim to fix the focal plane distance. I tried making the shim but found that I needed to make something that was about 1/2 a millimeter in thickness. Of course I did not have the tools to do this so I had to improvise.

I needed something that would be relatively rigid but would allow for some compression before setting. The solution, Hot Glue. By laying down a small bead of hot glue on the adapter I was able to set the lens to a specific focal distance then adjust the lens into the mount until the focus was sharp. And it worked.

Because the image circle is less than that of the full 4/3 sensor we need to use the teleconverter mode to crop into the image circle. With this done the lens effectively becomes a 70mm to 200mm F1.8. Considering I paid $170 dollars for the whole setup I can't imagine how much a normal 70mm - 200mm F1.8 lens would cost even if one were made.

I'll be keeping my eyes open for more great C Mount lenses like this one to add to my video lens collection. Now I need to find a good low light shooting situation to test out this wicked fast piece of glass.

Cheers,

Mark
