This review is for the Bushnell H2O Roof Binoculars sizes 8x42 and 10x42, both of which I recently purchased. These binoculars are inexpensive but have many of the characteristics of expensive binoculars. They are water and fog-proof, they have BaK-4 prisms, and they have a well-constructed and rugged body. I purchased roofs rather than porros after my Nikon porros lost their collimation. Nikon repaired them for $10 plus shipping (which was very fair), but I did not want to go through that again. Roofs are generally more durable. These binos appear well collimated (I did every test I could find on the internet, including shining the sun through them onto a screen), they can quickly be focused quite sharply, and there is very little color aberration. The 8x42s have remarkably little distortion near the outside of the field of vision; the 10x42s have more, but are still quite acceptable. The eye relief is good, so I can wear these with or without glasses. The rubber eyepiece collars are a little hard, but I purchased Field Optics eyeshields (I have no interest in the company) which both shield outside light from entering from the sides and soften the feel of the binoculars against the eyes. Both binos feel slightly heavy for their size, but are really okay. The straps require some lacing, but if carefully done, are okay too. The case is slightly tight, but acceptable. The front and rear lens covers can be attached, which is great.The biggest problem with these binos is that they are roof binoculars with only multicoating. They are not fully multicoated nor phase coated. The lens quality is good, but not great. Thus the images are clear and sharp, but not as bright as you might get with a porro of the same class or an expensive roof bino. In good daytime light, this does not matter, but in really overcast light, the view is acceptable, but could be better. Not surprisingly, the 8x42s are brighter than the 10x42s. However, at night, using a tripod, I prefer the 10x42s since they permit better viewing of the moon and the stars. Surprisingly, the focus is so sharp that I can produce pinpoint images of Jupiter without flaring.Thus we have inexpensive binoculars pretending to be expensive binoculars and doing a pretty good job of deception. The muted brightness is only a problem in poor lighting, but otherwise these binoculars are impressive for their price. I give the 10x42s four stars and the 8x42s four and a half stars.
