[QUOTE="ceasar, post: 3506592, member: 26155"] Rev, I might be wrong, but I think that along with FOV you are also talking about DOF, ("depth of field") here. When you are walking about "in the woods," as you noted, a 10x binocular can really be "a little much" when it comes to finding the "sweet spot," which, I think you mean, is the spot that is in focus. That is because, compared to a 7x or 8x binocular, a 10x binocular has very short depth of field so when you are looking though all those tree branches trying to follow a bird, like a warbler, near you, most of what you are seeing will be out of focus unless you can rapidly turn your focus wheel to follow the bird. If you are using a 7x42 binocular lots of those tree branches that the bird is flitting about in will be in focus so you can follow the bird through them much easier with only small adjustments of the focus wheel. Also, 7x and 8x binoculars almost always have wider fields of view than 10x binoculars do and for that reason they are easier to use during a walk in the woods than 10x binoculars are. In short, for this kind of use, I think 8x binoculars will be a lot better for you than 10x will be. 7x binoculars are hard to find anymore and all of them are expensive. You can order good Nikon 8x42 Monarch 7 ATB binoculars through Cabelas on line. They have a wide 8º FOV or 420'@1000yards and cost about $480.00. They have long 17.1mm eye relief. Bob [/QUOTE]
