What is the lightest 8x42mm roof prism made? My vote goes for the Nikon Monarch 8x42mm @21.5oz. If you know of one lighter let's hear about it. If you know of a lighter 8x42mm porro let's hear about that too. Please give weights in oz. This is a contest JUST for weight!
I wouldn't rely too heavily on manufacturers' quoted weights. They can vary by +/-10%, usually plus!
I don't think a few more ounces are going to cause any serious discomfort and weight reduction may entail compromises in optical and mechanical quality.
IMO too many consumer products have their benchmarks dictated by marketing people instead of engineers so that the manufacturers can advertise an irrelevant superlative.

A second vote for what is the point of the question???
The Nikon Monarch ATB is a candidate for one of the lightest, over-hyped/over-rated, becoming anachronistic (compared to lower-priced, optically advanced also Chinese- made albeit slightly heavier) 8x42 binoculars with a not so impressive FOV of 330 feet.
