I just bought a c-mount lens and need to have it modified for my gh2 so I can focus to infinity. Any recommendations for someone who does this work? Thanks.

I have an adapter, but it wont focus to infinity, it needs to be modified.
You could try duclos, not sure if they do this kind of thing, but worth a try.

I have a Cosmicar 12.5 f1.4 that needs to be modified.

I've modified the Computar 12.5 f/1.3. Wonder if it's kind of the same? For the Computars, I read that a screw can be taken off from the focus ring that allows it to turn farther past its infinity mark. Do you know of the Cosmiscar could do the same? But anyway, removing the screw didn't solve my problem. I had to physically wear down the rear barrel so the c-mount adapter could screw in deeper hence shift the rear closer to the sensor to achieve infinity.
I can show you samples if you like. PM me if you'd like me to modify it but you'd have to ship it to Hong Kong!
