Shed..The camera/ binos I've seen are nothing more than a cheap pair of binoculars and a digital camera. The zoom on the Binos in no way had any bearing on the zoom of the camera. They are basically 2 seperate entities in one housing.
There may be better ones now-a-days ...if so let me know.
I've been looking into some spotting scopes that incorporate a digital camera and from the price tag I assume they work quite well.
