What to know before buying
Listing details to confirm
The listing claims waterproofing, and a feature description further claims IPX8 protection, nitrogen purging, fog resistance and sealing against immersion. These protection details are not consistent in specificity, so confirm the exact rating and conditions before relying on them. The stated 22.0 eye relief is also distinct from a feature description of 22 mm eyepieces, which is not the same measurement. The listing's claims of 90-95% light transmission and rapid 1-5-second focusing are promotional claims rather than independently established performance.
