Buy KOWA SV II 10x50 binoculars – the twilight specialist with a 50 mm objective

The KOWA SV II 10x50 is the brightest binocular in the SV II series. Its 50 mm objective gathers more light than the 42 mm models – a decisive advantage for twilight observation. With a twilight factor of 22.4 and relative brightness of 25, the SV II 10x50 delivers bright, detailed images when other binoculars have already gone dark. 10x magnification brings distant subjects close, and fully multi-coated optics ensure maximum transmission. For evening stalking, wildlife counts at dawn or casual astronomy, the SV II 10x50 is your low-light specialist. Buy from Swiss-Sale.ch – your Swiss specialist for optics.

Light Gatherer · 50 mm

50 mm objective – why 8 mm more make all the difference at dusk

Jumping from 42 mm to 50 mm objective diameter means roughly 42% more light-gathering area. At dusk, when every photon counts, this produces a noticeably brighter image. The twilight factor climbs from 20.5 (10x42) to 22.4, the exit pupil from 4.2 mm to 5 mm. For hunters who must identify game in the last shooting-light minute, and ornithologists on evening owl excursions, the SV II 10x50 is the logical choice.

10x magnification – sharp detail at distance

The 10x magnification of the SV II 10x50 brings a deer at 200 m as close as one at 20 m with the naked eye. The 87 m field of view at 1,000 m (5°) is typical for 10x50 binoculars and allows precise observation of individual animals or landscape details.

Waterproof and nitrogen-filled – reliability at night and in fog

The SV II 10x50 is fully waterproof and nitrogen-purged. Fog-free optics are critical at dusk: when you step from a warm hide into evening coolness, the image stays clear. Twist-up eyecups with 19.5 mm eye relief accommodate spectacle wearers.
