Fluorite Spotting Bino Completed

This should be the final version as 50mm fluorite spotting bino.

Since it is F8 optics, there is little vignetting. Very compact and good weight balance. Quite easy to carry and walk around in the field. This has become my most favorite spotting scope. This system has capability of binocular-like binoviewing comfort as well as spotting scope-like magnification.  Moreover, it creates the clean and sharp image by the fluorite crystal and BORG erecting prism, which allow to push to 100x magnification if wanted. 71FL should be nice too. But Since it is F5.6, 50FL should be just good enough at the view point of the effective aperture and the cost.  If someone is looking for high-power terrestrial viewing by both of eyes, I highly recommend this system. This should be the winner (or no competition)  in the field since no other brands/optics can do that. I plan to prepare for the complete set.
