This may not be the coolest looking telephoto lens mod out there, but it just might get the job done. It only requires a bolt, some cardboard, a few twist ties, and binoculars. I am not sure this will hold up to moving around, but for that one telephoto shot you want to make, why not give it a try? – Link

I tried this today worked great!
Minox had an adapter for their push-pull spy style cameras that did this exact same thing. They work great. They even incorporated a shutter release holder.

I’ve tried this in the past with reasonable (but not great) results.
