Finding a wide angle fast lens for the GH1 is a problem. There are simply none available. Vivek from GetDpi played around with the Fujinon 12.5mm f1.4 and modified it to get full coverage. This is my attempt to do the same.

Tools used. DIY Rubber tool for unscrewing recessed lenses and a set of lens spanners. Not shown here but also used is a small screwdriver from a 2$ jewellers set of tools from DSE.
Rear element. The rear element was removed with a lens spanner. The glass element is not attached to anything and will fall off, so be careful.
Front element. The front element was first loosened with the lens spanner and then unscrewed with the rubber tool.
Lens body and focus ring/hood. There are 3 small screws in the focus ring that come off with the jewellers screwdriver. Then the 2 parts easily separate.
Top view of hood/focus ring and lens body. This view shows the brass helicoid (??) that is involved in the conversion. We can also see the shutter in the lens body.
