Leupold BX-5 Santiam HD 12x50 Binoculars – 175856

The Leupold BX-5 Santiam HD 12x50 Binoculars, part number 175856, are a full-size open-bridge magnesium roof prism binocular delivering 12x magnification on 50mm objectives, with a field of view of 91 m at 1,000 m (272 ft at 1,000 yds) and 16.6 mm of eye relief, at 910 g (32.1 oz).

Behind the 50mm objectives sit phase-coated BaK4 roof prisms and Leupold's Professional-Grade Optical System, with DiamondCoat 2 on the exterior lens surfaces and the Guard-ion hydrophobic coating that sheds rain and fingerprints. The open-bridge magnesium chassis is rubber-armoured and 100% waterproof and fog-proof, focuses down to 3.5 m (11.4 ft), adjusts from 56–74 mm between the eyes, and carries twist-up eyecups and a built-in 1/4-20 rotatable tripod adapter port.

How It Compares

The 12x50 trades field of view for reach within the BX-5 Santiam HD line: 91 m at 1,000 m (272 ft at 1,000 yds) against the BX-5 Santiam HD 10x50's 101 m, on the same 50mm objectives and for only 17 g more at 910 g (32.1 oz), with eye relief dropping from 19.3 mm to 16.6 mm. If you glass from a high seat or a rested position it is the better of the two 50mm models; if you scan on foot, the 10x50 or the lighter BX-5 Santiam HD 10x42 at 689 g is easier to hold.

Frequently Asked Questions

Is 12x50 the right format for UK stalking?12x50 suits rested glassing rather than walking. At 12x the 91 m field at 1,000 m (272 ft at 1,000 yds) is narrower and the image harder to hold steady freehand, so it comes into its own from a high seat, a rest or the built-in 1/4-20 rotatable tripod adapter port.

Will the BX-5 Santiam HD 12x50 work with spectacles?Eye relief is 16.6 mm and the eyecups twist up and down, so you can wind them flat, keep your spectacles on and still see the full 91 m field at 1,000 m (272 ft at 1,000 yds).

Will it stand up to British weather?The BX-5 Santiam HD 12x50 has a rubber-armoured open-bridge magnesium chassis and is 100% waterproof and fog-proof, and the Guard-ion coating sheds rain and fingerprints from the exterior lens surfaces.

Can it be used on a tripod?Yes — the BX-5 Santiam HD 12x50 has a built-in 1/4-20 rotatable tripod adapter port, which is worth using for long spells glassing one hillside.

How does it compare with the 10x50?The BX-5 Santiam HD 10x50 shares the 50mm objectives and weighs 17 g less at 893 g (31.5 oz), with a wider 101 m field at 1,000 m and 19.3 mm of eye relief. Choose the 10x50 to carry and scan, the 12x50 to sit and judge.

Is this genuine Leupold stock?Yes — factory-new Leupold stock dispatched from the UK.
