This time of year, I get asked about the difference between an
8x42 binocular and an
8x50 binocular for
hunting. Most hunters, of course, are out right at first light or last light, when animals are most active, and they want a binocular that offers the best image brightness. So is the larger lens of an 8x50 binocular really that much better? After all, that 8x50 binocular will be heavier and bulkier, not to mention more expensive, all else equal. In my experience, out in the field where it counts, under the darkest conditions, my vote is no. I've seen very little difference in image brightness between an
8x42 binocular and an
8x50 binocular, when comparing binoculars of the same brand and series. Of course, I am way past forty, now, and my eyes can't use all the light delivered by an 8x50. Still, even in my younger years, I did not notice enough of a difference to justify the 8x50, but that's me. With
binoculars, there is a lot of psychology involved. If you think something works better, you have more faith in the product and you are more likely to use it and trust it. That's reason enough to buy an 8x50 binocular.
