Need to adapt a fiber optic as a lens to a video camera lens, can anyone help me out?

have you priced fiberoptics? seems to me it would cost a whole lot less to
get your self a color pin hole camera and rig it to a tiny flashlight. a
new fiberoptic that would act as a lens extention would probably cost more
than a new car. check ebay for surplus medical endiscopes

 

Basically, the fiber optic lens will be an extension to the video camera lens so that light going through the fiber goes
directly into the video camera lens. We have several trees in our back yard and we want to look inside some of the holes
in the tree to see what is inside it. How to make a fiber optic light source would be useful to. Thanks for your time.
