 Equivalent focal length of binoculars?
Every now and then I look at Binoculars and all they say is 10x25 (10 being the 'zoom' and 25 being the size of the objective lens). So I was wondering what is the zoom on binoculars equivalent to on a 35 mm camera? Any help would be greatly appreciated =)

The "zoom" as you call it is actually the magnification. 25 in this case is the size of the objective in millimeters. There is no equivalent to a 35mm camera because 35 refers to the size of the film, not to any of the lenses. Interchangeable lenses can give you nearly any configuration you want with a 35mm camera.
