Message: <blockquote data-quote="spyglass" data-source="post: 1815895" data-attributes="member: 18470">Jerry, the afov is the actual (in degrees) mult by the power of the bino....e.g. a 7x glass w/an 8*fov actual has a 56* apparent field of view (afov). 10x w/a 6* is 60* afov, and so on. Now, Nikon has come up with a new formula for afov and theirs shows something like 55* now for (e.g.) the 10x42, rather than 60*. But the afov is what it is, regardless of the stated figure. The higher you go in mag, the lower the actual fov has to be to get the same effect. When the SE's first came out they had respectively 7.5,6 & 5 for the 8x,10x & 12x, but all were 60*afov, which is considered the minimum to be termed "wide-angle".I'm surprised everyone thinks the Discoverers are big & heavy. Mine weighed 32oz and were about 6" tall. I just always thought of it as substantial....solid....rugged, all of a piece. It was probably the most comfortable bino to hold of the 75 or so I've had over the years (along with the Canon 15x50IS). It's definitely my candidate for best roof under $400.....(at least the 7x was....never tried the 8x or 10x).</blockquote>
