As a new digiscoper, I was looking for digital camera adapter to handle a somewhat large Minolta ZX camera with a Kowa 601 spotting scope. The Alpen 706 adapter turned out to be perfect for this. Instead of clamping onto the scope's eyepiece, like most of the (too-)small adapters, it screws into the mounting plate of your tripod, and the spotting scope and camera are mounted on the adapter. Stability and balance are thus very good, and Alpen includes the convenient ability to swing the camera out of the way to use the scope for straight viewing. Once adjusted to the camera, it was quick and easy to set up. I successfully produced digiscoped photos within about an hour. Being somewhat large, it is a little less portable than the clamp-on adapters, which may slightly limit its use in the field. The manual was well-written and even included photographic advice on digiscoping. Much cheaper than dedicated spotting scope adapters, it should even work with most digital SLRs. A real winner!
Pros: Sturdy, versatile, good for larger digital cameras, much cheaper than dedicated adapters
Cons: Somewhat less portable than clamp-on adapters
