These binoculars from Olympus are part of the Premium Porro line. The Olympus 10x42 EXPS I is equipped with coated glass and aspherical lens elements that provide you with a razor-sharp image. Thanks to the robust grips, you can hold the binoculars for a long time without pain or cramping in your hands. The 10x magnification is suitable for sports, safari trips, or birdwatching. The exit pupil is 4.2mm, just large enough to use the binoculars in the dark.
