Swarovski bets on field of view with NL Pure binos
June 30, 2020
Forget light transmission, forget ease-of-use – they are last year’s optic USPs. Swarovski’s three new binocular launches pushes a new boundary: it’s all about field of view.
With its NL Pure, launched on 1 July 2020, Swarovski wants to immerse you in your view by offering a market-leading 71-degree ‘apparent’ field of view.
No detail on why the use of the word ‘apparent’ but the new binos are a lens system the same as the Swarovski EL, so it is not digital manipulation.
“In the past, we have talked about edge-to-edge sharpness,” says Swarovski spokesman Wolfgang Schwarz. “But there is one thing that’s even better – no edges at all.”
The 8×42 NL Pure field of view is 159 metres at 1,000 metres. The 10×42 offers 20% more field of view that the Swarovski EL 8×42. And, for the first time, Swarovski is offering a 12×42,
an NL Pure that has a field of view with 130 metres at 1,000 metres that beats the EL 10×42’s 112 metres at 1,000 metres.
And did we say forget light transmission, forget ease of use? Forget that. Handling is still a thing. By rotating the prisms to right angles, Swarovski has slimmed down the middle of the tubes.
That helps the NL Pure fit your hands more easily.
Light transmission is 91%, the same as the Leica Geovid and 1 point down on the Zeiss SF.
The NL Pure 8×42 weighs 840g, which is about 10% more than the Zeiss SF 8×42. but more than 10% less than the Leica Geovid 8×42’s hefty 950g.
Shipping begins 1 September 2020. Price is €2,850 in Austria and US$3,299 in the USA for the 8×42.
The NL Pure is not a replacement for the Swarovski EL binoculars – ‘don’t mess with the legend,’ they tell us gravely – but Swarovski staff point out that the new model is better.

So beside the specifications, of most interest is:
• The reference to rotating the prisms 90 degrees (?) to enable the more ergonomic design, and
• That the NL is not replacing the EL (and nor presumedly the lower priced SLC)
And it’s probably useful to add:
- The apparent field of view is no mystery, it's the combination of the actual/ angular field of view, together with the effect of the magnification provided by the eyepiece
- Saying that the lens system is the same as the EL, is not saying that the lenses are identical, and
- The listed transmission of 91% is one percent more than that of the EL's, and the same as that of the x42 SLC's
