Buying a Binocular - Mid level

just sharing the research outcome for binoculars, may be useful if you want to buy one in future.

8 X 40 (8 X 25 is a little lighter)
Exit pupil – 5mm
BAK – 4 lenses
Prefer Roof prism, though it will make it little expensive. Porro prism, less expensive, but a little heavier
Fully multi coated lenses preferred (fully coated are a NO, multi-coated acceptable)
Diopter adjustment is sort of essential
Eye relief – 14 / 15mm, more the better, upto around 17 mm
Weight – upto 30 ounces is good to carry on nect, else shoulder straps should be used
waterproof - just desirable, helps in rain, if accidentally falls in water etc.
Armoring helps as it provides more protection to the body (it is rubber cover)
