Detailed Review and Analysis of these Steiner binoculars

  • Free focus technology

There are not many open bridge porro prism binoculars on the markets. Most of them come with a central focus wheel between 2 bridges. However, the free focus technology allows Steiner to remove that wheel so that you can enjoy a better view with depth.

As they are always in focus, you can conveniently use them with one hand. The common drawback of free-focus binoculars is the long close focus. Luckily, Steiner has innovated the system to achieve 18m shortest focusing distance in this model.

  • Produce bright images with good quality

The unique Color Adjusted Transmission (CAT) strengthens the orange-brown colors while reducing the intensity of green ones. That function is extremely beneficial for nature observers or hunters in some particular environments.

The FMC lens coating of Steiner Predator AF 8×30 minimizes the anti-reflection to offer you brighter pictures with high contrast. Even in moderate light conditions, these binoculars still perform well. Nonetheless, if you want something to exceed in total darkness, you may have to sacrifice the weight and size to choose other full-size options.

  • Lifetime warranty

Unlike other brands, Steiner shows their highest commitments to their products through the Heritage Lifetime Warranty. The policy covers all the charges, and Steiner is responsible for all the damage, as long as it affects the binoculars’ performance. 

Don’t worry if you are a secondary purchaser since that warranty is transferable, meaning your item is always under protection.

Weak points and notes

  • Narrow field of view

These 8x binoculars offer a relatively narrow field to you. That means it would be challenging for you to observe fast-moving objects at a closer range. However, it is not a big issue for hunters when observing targets at the medium and long-range is far more important.

  • Fold-down eyecups

The soft rubber eyecups are great, but the fold-down design is troublesome for users with glasses. That is because they can only choose to have either full or minimum eye relief. Some people are fine with this lack of customization, but you had better note that in mind.
