[QUOTE="Kevin Purcell, post: 1348281, member: 68323"] Where did you get the AFOV numbers from? Using the usual approximation (that over-estimates AFOV) this should be 64 degrees vs 56 degrees which you would notice (unlike the 58 vs 56 you mention). Beware that in their product literature Nikon is using the "correct" method for calculating AFOV which would come up with a smaller number than 56 degrees. Not sure if Bushnell is doing that too. You need to know to compare Apple's to Apple though as they're both 8x then it just scales as the FOV (8.0 degrees vs 7.0 degrees). The advantage of the smaller FOV is it reduces issues with stray light (it would be nice to see someone try this by comparing these two bins "close" (20 degrees or so) to a low sun ;) ). [/QUOTE]
