Pentax to spotting scope interface - Bushnell 35mm T-Rings Camera Adapters

I am using this adapter to connect a Pentax K7 DSLR to my Bausch & Lomb PremierHDR spotting scope. To do this, you need both a T-ring adapter and Bushnell's camera adapter, model number 780050, also available from Optics Planet. The setup works perfectly, but I found I needed to tighten the set screws on the T-ring with a small hex wrench. Otherwise, the T-ring would just spin/freewheel on the camera adapter and wouldn't actually attach.
Pros: Good quality; works as intended
Cons: Need a small hex wrench (not supplied)
