[QUOTE="ronh, post: 1223574, member: 55514"] OK, I'm in the Leica forum this time, and will try this again! My 8x42 Trinovid BA loses 9% of the light right off the top due to the silvered, rather than dielectric prism coating, but would like to discuss and ask about the antireflective coatings. Astronomers are constantly staring into their binoculars and judging coating quality by the difficulty of seeing reflections. This is like sniffing barrels instead of drinking whiskey, but it tells you something. The BA coating looks good on the eyepieces, but not so hot (compared to say Fujinon FMT-SX or Swaro EL) on objectives and prisms. In fact, its view is not quite as bright, but in real life low-light situations it performs as well as my wife's 8.5x44 EL. Now here is where it gets strange. In very bright light, I actually prefer the Trinovid. I don't know what happens to the lost light, but itdoes not seem to be scattering around polluting the view. The colors look deep and highly contrasted, and the view is kind of cool and relaxing. I am sort of new to daytime bino use, and probably don't express this very well. So, questions are: Is there a 1-800 number I can call for help with this perverse rationalization? I am crazy, right? Are the latest coatings on the Ultravid better looking those on my BA? If the Ultravid is noticeably brighter, has the bright-light comfort and contrast been compromised, or is it just flat better in every conceivable way? Sorry, this was so rambling. Thanks, Ron [/QUOTE]
