Review: Bostron 10x50 binoculars $30

Amazon Affiliate Link: https://amzn.to/4shSC4e Price as reviewed: $30 10X50 Binoculars for Adults High Powered with BAK4 Prism FMC Lens, Low Light Vision & Large View, Waterproof Compact Binoculars for Bird Watching Hunting Sports Travel, Carrying Bag & Strap From the BOSTRON Store These are generic binoculars with 8-9x magnification and 50mm objective lenses. The one unique feature is that both eyepieces have independent diopter adjustment via thumb levers. When I first saw the thumb levers I thought that perhaps the binoculars had independent zoom adjustment, but they just adjust the focus on each eyepiece. (There is also a standard center dial that adjusts the focus of both eyepieces simultaneously for changing focus when you change the distance to the target.) The thumb levers make it easy to focus each eye, and don't get in the way when using them, but may be bumped in the storage bag and need to be re-adjusted on the next use. It's an interesting feature, and I don't hate it, but I'm also not looking for future binoculars to have it as a "must have" feature. Optically they are reasonable, but not excellent. (You wouldn't confuse them with a brand name pair of binoculars, but they are also 2-3x less expensive.) Clear views, good light levels, reasonable sharpness. Comfortable eye relief and large exit pupal. For the price point, it's a good deal.
