The Olympus 8x42 EXPS I binoculars are a great choice for everyday general use. They offer a reasonable 8x magnification combined with a wide 42mm objective lens diameter which provides an apparent field of view of 52°. With a rubber coated construction and a long eye relief, the binos are comfortable to use and feature a large focusing dial for improved control.

8x Magnification

Binoculars with am 8x magnification, like the Olympus 8x42 EXPS I model, provide an excellent balance that can bring far away subjects closer, while at the same time making them easier to find. This is especially useful when following moving birds or animals, helping you to track them without getting lost and also reducing shaking.

Effective Objective Lens Diameter of 24mm

The objective lens on a pair of binoculars defines how wide the field of your view is as well as the relative brightness. At 24mm the 8x42 binoculars are able to collect more light allowing them to be used in darker conditions.

High Index Porro Prisms

Using a porro design, the binoculars have BaK-4 prisms, considered to be the best type of porro prisms because of their ability to produce clear images. The BaK-4 Prisms have a high index and are designed to stop internal light scattering to enhance sharpness.

Optics with Multi-Coating

Fully multi-coated lenses maintain brightness and contrast by controlling reflections to improve the quality of light transmission. This combined with the UV coating ensures that you appreciate the clearest view possible.

Ergonomic and Easy to Use

The Olympus 8 x 42 EXPS I binoculars are designed to be comfortable and ergonomic with a rubber coated body construction and a long 18mm eye relief that makes them perfect for people who wear glasses. A large control knob between the eyecups allows easy changing of the focus and an integrated dioptric adjustment allows correction for individual eyesight.
