What’s not to like?

While the Swarovski EL 10×42 binoculars boast many outstanding features and qualities, there are a few aspects that some users might not find appealing:

  1. Premium Pricing: The EL 10×42 comes with a premium price tag, which may be a deterrent for budget-conscious buyers or those new to binoculars who are hesitant to make such a significant investment.

  3. Limited Eye Relief: While the eye relief is adequate for most users, eyeglass wearers might find it insufficient for comfortable viewing. In such cases, alternative models with longer eye relief may be more appropriate.
  4. No Tripod Adapter Included: For those who wish to use the binoculars on a tripod for added stability or extended observation sessions, a tripod adapter must be purchased separately, adding to the overall cost.
  5. Expensive Accessories: Swarovski accessories, such as cases, straps, and cleaning kits, can be relatively expensive compared to those of other brands. Users who require additional accessories may need to factor in these costs when considering the overall investment.

While these drawbacks may be relevant for some users, the Swarovski EL 10×42 binoculars still offer exceptional optical performance, ergonomic design, and durability that outweigh these potential concerns for those who prioritize quality and performance above all else.

What are the main differences between EL and NL Pure? Why would one choose one over the other?

The Swarovski NL Pure series is a more recent addition to Swarovski’s lineup, building upon the success of the EL series. Here are the main differences between the Swarovski EL and NL Pure binoculars, along with reasons why one might choose one over the other:

  1. Field of View: The NL Pure series offers a wider field of view compared to the EL series, providing an even more immersive viewing experience. For those who prioritize a panoramic perspective, the NL Pure series may be the preferred choice.
  2. Ergonomics: The NL Pure series introduces a new ergonomic design with a unique forehead rest, called the “FRR” or Field Rest, that provides extra stability during observation. If long observation sessions are common and additional support is desired, the NL Pure series may be more suitable.
  3. Size and Weight: The NL Pure binoculars are generally more compact and lightweight than their EL counterparts, making them more portable and easier to handle. For users who value a more compact design, the NL Pure series could be the better option.
  4. Design Aesthetics: The NL Pure series features a more streamlined and modern design compared to the EL series. Users who appreciate the latest design trends might prefer the NL Pure series.
  5. Price: The NL Pure series tends to be more expensive than the EL series due to its newer design and additional features. For those on a tighter budget or who find the improvements in the NL series less crucial, the EL series may be the preferred choice.

In summary, the choice between the Swarovski EL and NL Pure series largely depends on individual preferences and priorities. If a wider field of view, enhanced ergonomics, and a more compact design are essential, the NL Pure series might be the better choice. However, if the additional features do not justify the higher price tag, the EL series remains an excellent option, offering exceptional optical performance and durability.
