I have a few. The problem in knowing what to buy is that the sensor is 4/3. Very few CCtv lenses were made for that size sensor. So try to get one for a one inch sensor. At a pinch, 2/3 lenses will do. But there will be a lot of vignetting and the coverage will mean a pic of 3-4megapixels only. The central part of the sensor only will be covered. Some lenses will do better than others.
Buy only if under $20 and have fun trying it out. Sell on telling the buyer what you could see?
Have fun above all!

i would expect lots of vignetting using ANY c mount lens under 25mm--so much so i think many might consider them pretty unusable except for trying to achieve a very specific effect. i wouldnt pay more than 20-30$ if that much!
OT, i just received the 75/1.4 and i like it very much, tho its bigger/heavier than expected...

our local m4/3 group bought and tried a couple of c mounts as large as 108mm, and we find the Pentax 25mm f1.4 is the best for m4/3. it is however a new lens not used, so the price is higher but it does come with a year's warranty.
