Sorry I measured them compared to other known 8's and 10's.BAK-4? wouldn't bet on it for this price and non ISO standardized company, lol.Time will tell but these still seem pretty good.IX57? lol what does that mean? Sounds like a steak sauce.These are NOT waterproof by any means.I left these on my porch with some other binoculars for evening viewing, and we had a fairly gooddew as temps dropped.ALL of them, including these, fogged on the INSIDE of the binocular.Id not take them on a once in a lifetime safari, but I'd use them everyday on my porch and be quite satisfied with their clarity for $10. ### ⭐⭐⭐⭐ Ultralight spare bino *by S***G on Reviewed in the United States on September 20, 2019* Its so light it practically disappears on your belt. I hardly feel it, obviously its no contest to my Orion 20x80 but its definitely a good binoculars to tote along hiking ultralight where you did not envision a need for a binocular. Its size made it an interesting conversation piece too. People often and ask about it and they are amazed to see through it and realize its not just a toy. It is especially well received by kids.It feels cheap but so far its been fairly durable. Its been rained on... and survived. Most of the time I carry it into orchestras or choir concerts. Its been a hit with the other audiences.cons: mostly the pouch... the Velcro section on the flap is a tiny square and pretty much rendered useless after a few openings. I stitched on a wider strip and that fixed that. ### ⭐⭐⭐⭐ Very nice for the price! *by D***B on Reviewed in the United States on August 23, 2021* Nice for car trips and casual birding. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/106406416-binoculars-for-adults-10x42-bak-4-roof-prism-fmc-lens](https://www.desertcart.jp/products/106406416-binoculars-for-adults-10x42-bak-4-roof-prism-fmc-lens) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-09*
