In the course of making a wide range of products to suit the Americans taste for shooting anything that moves, they produce a range of binocularsideal for the gentler, more British pastime of pony spotting - often referred to as birding. One flaw that distinctly stands out for such an expensive pair of 8×32 binoculars is the smallish field of view which only offers 400’. On the other hand, these Zeiss binoculars also employ the high-quality Schmidt-Pechan roof prisms while providing excellent water and fogproofing from LotuTec coatings as well. Pros

By fully closing the hinges, the minimum IPD on the 8x32mm NL Pure is 5.4cm, which is very close and thus these should accommodate those with very close-set eyes.If you do wear glasses, eye relief becomes a lot more important. It’s usually accepted that you need at least 14mm of eye relief to see properly through binoculars while wearing glasses. In that respect, the 20mm that we see on the Swarovski Optik EL is more than enough for comfortable viewing. Exit pupil

All high-quality binoculars rely on great optics. A large part of this comes down to the quality of the glass used and the coating on the optics. For instance, multi-coated optics such as on the Sightron SII reduce the loss of light due to reflection and ensures the highest levels of light transmission.

That said, you do have to pay for quality, and the Carson 3D Series binoculars are not an inexpensive pair.
