Hello, recently acquired a mint condition zen-ray neptune 25x100 binocular from Craigslist. Haven't been able to find any information on the web relating to this binocular. I have several other sets of binoculars to compare them against-- the nicest set being a nikon lx hg. The nikon has exceptional optics edge to edge, fantastic resolution and clarity. I was astounded when I compared the zen to the nikon. Overall the zen has just a very slight degree less color, contrast, and clarity. The image is very sharp edge to edge, and free of any noticeable distortion. I really wasn't expecting that type of image quality from this binocular. Anyway, just curious if anyone out there has any knowledge of this particular binocular. All I know is what is what is labeled on the back--fully multi coated, bak4 , waterproof. My guess is they're manufactured in the same facility as some of the other large binoculars (orion giant view, celestron skymaster, etc), as they appear nearly identical in design. Any feedback is appreciated!
