This review is for the 8x42 and 10x42 Bushnell H2O Roof binoculars that I recently purchased. These binoculars are inexpensive but have many of the features of expensive binoculars. They are waterproof and fogproof, with BaK-4 prisms and a solid and well-constructed body. I bought roofs not porros after my Nikon porros lost their collimation. Nikon fixed them for $10 plus shipping (which was very fair), but I didn't want to go through that again. Roofs are generally more durable. These binoculars appear to be well collimated (I ran every test I could find on the internet including sun exposure on the screen), it can be focused quickly and has very clear chromatic aberration. 8x42 has very little distortion outside of the field of view; 10x42 has more, but still quite acceptable. The eye relief is good so I can wear them with or without glasses. The rubber grommets on the eyepieces are a little stiff, but I bought Field Optics goggles (I don't care about the company) which both shield outside light from side rays and soften the feel of the binoculars from the eyes. Both binoculars feel a little heavy for their size, but they're actually okay. Belts need to be laced, but if you're careful you can too. The case is a little tight, but acceptable. You can attach front and rear lens caps, which is great. The biggest problem with these binoculars is that they are only multi-coated roof binoculars. They have neither full multilayer coating nor phase coating. The quality of the lens is good, but not outstanding. So the images come out crisp and clear, but not as bright as the same class of porro or expensive rooftop binoculars. In good daylight it doesn't matter, but in heavily overcast light visibility is acceptable but could be better. No wonder 8x42 is brighter than 10x42. However, at night with a tripod I prefer 10x42 as they give a better view of the moon and stars. Surprisingly, the focus is so sharp that I can create accurate images of Jupiter without any glare. So we have cheap binoculars that pretend to be expensive binoculars and are pretty good at deceiving. Dimmed brightness is only an issue in low light, but otherwise these binoculars perform well for the price.
