Lorson:

I have a pair of 10x70 Fujinon binoculars that are optically excellent. I bought them for astronomy. They are a bit heavy for most hunting applications, weighing in at about 77 oz, but I have used them pronghorn hunting, for example. I have had the binoculars about 12 years now.

Based on my binoculars, I would conclude that Fujinon is capable of making very high quality optics. At the same time, rifle scopes have special requirements that binoculars do not have -- such as withstanding high impact forces imposed by rifle gun shot recoil while maintaining the zero of the reticle.
