Field of view in binoculars/ + Cheap Binocular help

[BADGER.BRAD]

Hello all,

I'm a bit confused in the range of field for view advertised for binoculars some are advertised at 3.5 degrees and then others at 69 degrees is this right ? The range seems to far to me ! Plus I'm looking for a cheap pair of general use Binoculars (smallish light) to replace the old set of lead Zeppelin( size and weight) Carl Zeiss 10x50 ones I have ( fungus on the lenses) any recommendations. ?

There's a nice article here about how this works - you might be seeing 'angle of view' and 'apparent angle of view' quoted for different binoculars:

'The terms “angle of view” and “field of view” are complementary. Both terms describe the amount of scenery, measured horizontally, that is visible when looking through a binocular. Imagine standing in the middle of a giant pizza pie; binoculars with a 6.3-degree angle of view would show the viewer a 6.3-degree “slice” of the 360-degree pie, looking outward. Another way to express the viewing angle is the Apparent Angle of View (AAoV). This is roughly calculated by taking the AoV and multiplying it by the magnification. So if that 10x42 binocular from the earlier example has a 6.3-degree AoV, its apparent angle of view is 63 degrees.'

Here's a great place to get reviews of pretty much any decent binoculars you might be interested in:
