Hi, I'm former law enforcement and have owned and used several different brands of binoculars over my career, so I'm pretty familiar with which ones work well, and which brands are "Just Okay" That being said I had an opportunity to look at a pair of these Barska 9 power roof prism binoculars with 63mm diameter lenses for a friend that wanted them for watching birds and other wildlife. First, they're light, which is great for holding them up to your eyes for extended viewing. They also have "FULLY Multi-coated" lenses, meaning ALL the lenses inside and out are fully coated with chemical coatings that enhance light transmission. There are many binoculars on the market with only "coated" lenses, or "multi-coated" lenses which simple means only SOME of the lenses are treated. These Barska binoculars come with a rubber-like armored finish which protects them from moisture and impact. When I looked at their low light capability, I found that they had an extremely high light gathering index number of around 49. This is great when you're looking into a darkened area, or viewing in the evening. The 9x magnification also does a good job of bringing objects up nice and close, and with good detail. The focus wheel works smoothly as does the eyepiece's ocular adjustment. In short, having owned several pairs of top quality but expensive binoculars these Barska 9x63 roof prisim binoculars a great quality set of field glasses for a real affordable price (Usually around $80 to $90) The only thing that I could even come close to criticizing is that Barska used BAK7 glass for the internal prisms rather than the more expensive BAK4 glass, but that is a small technical difference that has little or no discernible effect to the average person. For the quality, and performance you get in return for the relatively small money you're spending on them, I'd give them 5 stars!Read full review

There are several good things about this binocular that will satisfy the needs with many optical instrument applications and budgets. These are sharp optically center and well across the standard size field of view, contrasty, built tough, long eye relief with fold down eyecups for use with eyeglass wearers, extra bright images dusk and into night for astronomy with average and younger persons eyes, water resistant, and being sold at a good low price. There are a couple of discrepancies in the common ad texts for these that may be useful for some of us to note. One is they are actually not truly FMC (fully multi-coated) as in each surface being as a multi-layer dielectric type coating for achieving a higher level of overall transmission from the front objective lens thru and ultimately to the eye of the observer. Some of the lens surfaces and at least the entrance surface of the prisms appear to be magnesium fluoride single layer metallic coatings. The reason product manufacturers and then sellers can specify a binocular FMC (fully multi-coated instead of just MC (multi-coated) is because there has not been an industry standard set for this specification. There are also binoculars that go as FC (fully coated with just magnesium fluoride single layer coatings and ones just called or shown as "Coated" which is supposed to mean some optic surfaces are metallic film coated and some are left uncoated. It is important and highly desirable to have as many optic surfaces coated in a binocular because an uncoated surface reduces light transmission by approximately 5% and when you add the total light losses up accumulatively thru an optical system in series in a binocular, it may only transmit 50% of the original light entering it by the time it reaches the eye. Lastly, the specification that the exit pupil is 6.3mm would be incorrect. Based on it being accurate they are 9x magnification, and a 63mm objective light cone is not clipped at the edges anytime going thru the system, it will then be a 7mm exit pupil, That would be the standard to bear. To determine this in general take 63mm and divide by 9 to get 7. For reference, my experience with optics goes back 28 years.Read full review
