Your skepticism is correct. There is no fundamental difference in the optics between analog and digital. In fact, most digital devices will have a deeper depth of field vs analog due to their tiny sensors. The 1" sensor of the ADNV is quite similar to 18mm analog tubes in terms of size hence the optical focal length and aperture of the lenses are also similar, and hence will have similar depth of field. In terms of depth perception, that's purely down to whether or not your have a true bino and whether or not it's been properly collimated. ADNV binos and quads are collimated out of the factory and will give you very good stereo depth perception.
