Fujinon 7x50 FMTR-SX Polaris Rubber Coated & Water Proof Porro Prism Binocular with 7.0 Angle of View U.S.A. Warranty -
The F-SX Type is a high-grade series of flat image plane-type binocular that encapsulates Fujinon technology. Making the image plane flat enables observation of the marginal area of a visual field, reproducis sharper, more true to life colors, and minimize distortions and astigmatism.
In the Fujinon "SX" series binoculars, every lens and prism surface is coated with a special new EBC process. The result is an overall brightness factor of 95% across the full visible spectrum - images up to some 15% brighter than any other high quality binoculars! Testing proved it. So will your own eyes. The benefit is outstanding vision in low light and at night - an especially important consideration in marine applications. Except for electronically amplified optical systems, such as those used in night vision scopes, Fujinon SX binoculars deliver the brightest image possible.
