I have the digiscope adapters for use with a nikon DSLR camera and a kowa spotting scope, I don't have any use for it any more, if someone could use it we could work out some kinda trade, when I did use it, it worked great, thou from what I have seen on most of them your auto focus system on your camera will not work. I think I spent like $300 for everything, with my kowa scope it worked out to be a 800MM lens, if you went to buy a nikon 800mm lens your looking at $10,000 big ones....ouch
