The Swarovski UCA is an adapter for digital single lens reflex (SLR) cameras and compact cameras. It will work with all Swarovski Spotting Scopes. For a quick change from observation to photography, and with the added benefit of being extremely secure, steady and compact. It is also incredibly light at only 12 ounces. Thanks to the innovative SWAROFAST function, you only need to adjust the position of your camera once in relation to your spotting scope. After this you can remove the camera from the adapter and bring it back into exactly the same position later without any need for readjustment. **these normally go for about $380 and $250 on clearance...check MidwayUSA or other retail** This is in used condition, the photo is the item for sale. Swarovski Optik is an expensive brand and if you are unfamiliar with spotting scopes or camera adapters, do your own research. My price is $140 OBO, this beats any price I've seen online. If you see it cheaper let me know.
