Very useful product -- i have some great footage from it. - Alpen Spotting Scope Digital Camera Adapter

I use it to mate a konus-100 to an hp r837 camera. We mainly do wildlife watching. It has been really fun to bring back stills and videos without spending much extra money. Now that I have the hang of it I probably spend as much time filming as just viewing.
Pros: Easy to switch between viewing and filming.
Cons: Requires some patience and practice to use well.
