5.3 mm exit pupil · 20 mm eye relief

Buy the KOWA SV III 8x42 binoculars – the bright all-rounder for woodland, dusk and long days afield
The KOWA SV III 8x42 binoculars are the classic full-size model of the SV III range – made for woodland birding, evening sessions on the stand and anyone who observes for hours without tiring their eyes. The 42 mm objectives gather considerably more light than a 32 mm compact: a 5.3 mm exit pupil, a relative brightness of 28.1 and a twilight factor of 18.3 are the numbers behind that. Add the longest eye relief in the series at 20.0 mm – the decisive argument for anyone who observes with glasses on.
Relative brightness 28.1 · the brightest model in the SV III series
5.3 mm exit pupil – why you keep seeing half an hour longer
The exit pupil determines how much light actually reaches your eye. In daylight the human pupil is roughly 3 mm wide – at dusk it opens to between 5 and 7 mm. That is exactly when a 5.3 mm exit pupil provides reserves a 32 mm model with 4.0 mm no longer has. In practice: the image stays bright and colourful for longer, outlines remain identifiable and you can still call a bird or a deer when others are already packing up.
20 mm eye relief – the full field of view with glasses on
Anyone who uses binoculars while wearing glasses knows the problem: you look through a keyhole and the edges vignette. The SV III 8x42 offers 20.0 mm of eye relief, the most generous figure in the entire range. With the eyecups twisted down you see the complete 7.2° field even behind strong lenses – no need to take your glasses off. The newly developed soft silicone eyecups lock in several positions and stay comfortable for hours.
Phase-corrected prisms and full multi-coating – natural colour, no cast
Kowa fits phase-corrected roof prisms throughout the SV III. They compensate for the phase shift inherent to roof prism designs and thereby preserve contrast and fine detail. Together with full multi-coating on every glass-to-air surface this produces an image with high light transmission and natural colour rendition – important when a plumage has to be identified correctly or when you assess an animal standing in shadow.
KR coating and waterproof housing – ready in any weather
The outer lenses carry Kowa’s KR coating: water beads off and dust and fingerprints adhere less readily. A single wipe restores a clear view – a genuine advantage in drizzle, fog or driving snow. The housing is waterproof and nitrogen-filled, so it will not fog internally when you move between cold and warmth. The grippy rubber armour absorbs knocks and holds securely in wet or gloved hands.
545 g in a redesigned body – balanced rather than bulky
At 545 g and 149 × 127 × 54 mm the SV III 8x42 is more compact than many binoculars in its class. The broad, smooth focus wheel operates with one finger and responds precisely – important when a bird changes distance quickly. Interpupillary distance adjusts from 56 to 72 mm and the dioptre correction sits on the right eyepiece. Beneath the centre hinge is a tripod thread for the optional Kowa KB2-MT adapter.

Why 8x42 has been the best-selling binocular format for decades
If you are shopping for hunting, birdwatching or general nature binoculars in Switzerland, you almost inevitably arrive at the 8x42 format – for good reason. Eight-times magnification delivers a steady handheld image without a tripod and without shake. The 42 mm objectives gather enough light for dusk and dense forest. And a 126 m field of view stays wide enough to follow a raptor on the move. The KOWA SV III 8x42 implements this proven concept with phase-corrected prisms, KR lens coating and a redesigned, more compact body.
