Panasonic GH2 + Pentax 6mm f1.2 lens

Seb Fargas encouraged me to toy with c-mount lenses on my GH2. The first lens i tackled was the Pentax 6mm f1.2 CCTV lens. This lens will not fit on c-mount adapters without further modification from the user or via professional modification of the lens. I personally decided to do the work my self rather then send it out, more fun that way right? I had to grind down the rear of the lens to get it to screw in further into the adapter’s thread allowing me to achieve infinity focus. Granted you should not do this at home without the proper equipment this is precision work and needs to be done professionally but none the less i did my own grinding with a power drill and a grinding rock. I eventually broke the rear of the lens and had to reassemble it using crazy & tape creating a new permanently adapted lens. It was still drying but I was eager to test it out so i mounted it on my camera as i ran around the city running some errands, here is the result. I will do a proper test for the lens sooner or later but for now i have included Sebastian’s Video under mine so you can get a better idea of what to expect but keep in mind you are viewing my home made performance vs a professionally treated lens =).

My Candid Impressions:

Seb Fargas’ Test

Below are some c-mount Adapters and Adapters lens combinations. Keep in mind what i said in the post some lenses will fit prefectly together with your adapter and some lenses will need adjusting to be able to reach infinity focus.
