I am a New Panasonic G1 user now and find a lot of amazing post here. Now I have a C-mount already and would like to try some TV lens on it. There is a term "machine" or "machining" for the lens. May some one explain why those TV Lens need to be machined and how can it be done. I have searched the old post but can't find some related "how to" topic of this matter. Would someone give me some idea of the technique that let my DIY myself?
Thanks for all of your sharing.
